Aeroelastic Analysis - GI - Poor Accuracy
Description
The linear splines used to connect structural and aerodynamic degrees of freedom are sensitive to modeling techniques, particularly on short-word machines. This included all machines except CRAY, CDC and NEC. It is good practice to have the spline axis coincide with the structural grid points, and to avoid discontinuities in the lines joining structural grid points by using separate splines on each side of the discontinuity.

Cyclic Symmetry - CYCLIC2 - UFM 3005, UFM 4319, UWM 4359 There are two errors related to the use of the CYSUP Bulk Data entry when rotational symmetry is applied to a model with three or more segments.
Description
1. If the rigid body rotations are to be supported, but there exists no stiffness at the components specified on the CYSUP entry, then UFM 3005 may be issued. But, if components 4 and 5 (out-of-plane rotations) are then constrained by an SPCi card or a GRID card, in order to avoid UFM 3005, then UFM 4319 will be issued. For components 4 and 5, an avoidance of UFM 4319 is to define rotational springs to ground (e.g., CELAS2). For component 6 (in-plane rotation), an avoidance of UFM 3005 is to apply a single-point constraint (e.g., SPCi), which is contrary to Remark 1 under the CYSUP Bulk Data entry description. b.

Executive - 3380 Disk Drives - Various System Errors (21OCT82) Users may not run any version of MSC/NASTRAN prior to MSC/62 on an IBM configuration that references 3380 disk drives. A variety of I/O related fatal messages may result from the earlier version's inability to compute blocksize correctly on these drives. The most likely messages are one or more of the SFM 4212 codes. Some users have had limited success by using half-track blocking with Version 61B. However, use of Version 62 is the recommended procedure. Furthermore, users may not copy (using IBM utilities) a MSC/NASTRAN database existing on non 3380 disks to a file usable by MSC/NASTRAN on a 3380 disk. (IBM only) This procedure may be accomplished however, by using a short MSC/NASTRAN DMAP sequence to read the existing file from the non 3380 disk and then write a

Miscellaneous - Shell Script Error - Unidentified Keyword on IBM RS/6000 An error exists in the IBM RS/6000 operating system that causes the NASTRAN shell script to incorrectly translate keywords resulting in an "unidentified keyword" error message being output during submittal of the NASTRAN job. The problem lies with the translate function. If a keyword is specified in uppercase in the nast675rc file, then it will be transposed by one character. The following example of the "tr" command illustrates the error: echo "FrEd" | tr '[a-z]' '[A-Z]' gRfD Thus, the valid keyword SDIR is translated to "tejs" and an unidentified keyword entry error results. Avoidance: This error may be overcome by using the "tr -A" option.

Nonlinear Analysis - MPC, MCE1 - Inefficient Restart If there are multiple subcases in a nonlinear statics restart run, and there are MPCs in the model, the MCE1 module is reexecuted for each subcase. This is true even if the MPCs are not modified from the coldstart run. If the MPC is not changed on the restart run, the MCE1 module should only be reexecuted for the first new subcase. This is because the transformation matrix between the m and n sets is not saved in the cold start run. Subsequent subcases should not reexecute the MCE1 module unless the MPC has been changed.
Description Avoidance: If the restart run has more than one new subcase and the MPC has not changed from the coldstart run, then insert the following DMAP alters to avoid this situation: COMPILE NLSTATIC,SOUIN=MSCSOU,NOLIST,NOREF ALTER 13 $ TYPE PARM,,I,N,FIRST=0 $ ALTER Known Error

In MSC/NASTRAN Version 67.5 this automatic acquire of NDDL=NDDL was inadvertently removed. This is an inconvenience to the user but more importantly the user who does not think he or she needs any data base access and hence does not need any NDDL for the user supplied DMAP will not acquire the appropriate timing constants that reside on the delivery data base.

Description
When performing nonlinear analysis, PARAM,AUTOSPC does not operate on the residual structure, PARAM,AUTOSPCR is provided for that function. However, PARAM,AUTOSPCR does not behave in the same way as AUTOSPC. It only operates on the o-set. Therefore, in nonlinear analysis using AUTOSPCR, many degrees of freedom may not be eliminated which would have been eliminated with AUTOSPC (e.g. DOFs 456 for solid models).

Acoustic Analysis - VELOCITY - Meaningless Answers for Complex Acoustic Results In acoustic analysis if the user requests VELOCITY=ALL in the Case Control, then "COMPLEX ACOUSTIC RESULTS" are output for the fluid grid points only and the standard complex velocity is output for the structure point. This is by design intent. However, if the user requests VELOCITY=setid and the setid contains structural and fluid points, then the program attempts to output "COMPLEX ACOUSTIC RESULTS" for the structural points and meaningless data is output.

Rigid Elements - GPSP - Wrong Answers
Known Error
Description
CR 5514 When some DOFs of a grid point are attached to rigid elements it may defeat the AUTOSPC function for the remaining DOFs. This was observed on a client problem where two rotations at one grid point were connected to a rigid element, but the third was not. It happens that this DOF has a very small stiffness due to a pin flag on a beam element. The stiffness would be identically zero except for roundoff effects. The evidence was that the eigenvector value for this point was 8 orders of magnitude larger than any other eigenvector DOF. Avoidance: A method to avoid this behavior, once observed, is stabilize this point with a stiffness value or other type of constraint. In this instance, when a ground spring of 1.E-10 was added to this DOF its eigenvector values approached zero. Another

The problem can be observed by setting the IPRINT parameter to at least four and observing the constraint values inside the DOT optimizer. Avoidance: The only known avoidance is to replace the DVPREL2 entry with a DVPREL1 entry. This, of course, is only feasible when the relationship between the property value and the design variables is linear.

Sequencer - SEQP, PARAM,NEWSEQ,6 PARAM,OLDSEQ,6 - SFM 4276, EC 3002 It is possible that jobs that request param,newseq,6 prior to Version 69 or param,oldseq,6 in Version 69 and after may encounter SYSTEM FATAL MESSAGE 4276, ERROR CODE 3002 in the SEQP module.
Description
By default sequencing in the SEQP module was turned off in Version 69 and beyond. PARAM,NEWSEQ was changed to PARAM,OLDSEQ to force the user to go out of his way to request sequencing. Thus, this error is considered corrected in Version 69 by the fact that sequencing is no longer recommended.

This leads to incorrect results for the output of the maximum and minimum stress. Avoidance: The CBEAM element should be used for Response Spectra Analysis whenever stress results are desired.

The REIGL module, when solving for normal modes of a vibration problem, under certain rare circumstances will perform many negative shifts and ultimately fail to find the modes requested by the user. Although one negative shift often proves useful in picking up rigid body modes, additional negative shifts are unnecessary and wasteful of computer resources. One way to duplicate the problem is to specify on the EIGRL card, F1=blank, F2=very large, ND=blank. If the F2 value is several orders of magnitude greater than the largest eigenvalue in the model, the shift logic will usually fail with the multiple negative shifts.

Postprocessing - XDB Limitation - Maximum Number of Grids There is a limit on the number of GRID points which can be processed by the DBC module for the ".xdb" file. The limit is dependent on many factors, one of the most significant factors is the solution sequence. For dynamic and nonlinear solution sequences the limit is 214748 GRID points. If more GRIDs than this exist in the model, some of the desired data may not be processed and placed in the ".xdb" file.
Description
Although there is still a limit on the total amount of data DBC can process, Version 70.5 contains changes that take into account the actual number of timestep or load steps actually solved. Thus, the program can more accurately predict the amount of data that it must process.

This can lead to incorrect responses in a subsequent modal response analysis. This error is most likely to occur if there are massless degrees of freedom and/or large mass in the model and the above conditions exist.

When part and grid list superelements are in one model, duplicated element ids in the list superelements are not detected. The results are difficult to predict. Some models have computed correct results, but it is possible that others would either give wrong answers or take confusing fatal exits.

When two DOFs are used a coupled mass matrix is produced. If not input correctly it may cause internal constraints. No checks are made for internal constraints in such elements. The following remarks should be added to the CMASS1 and CMASS2 Quick Reference Guide Descriptions: 7. Scalar elements input coupled mass matrices when the second pair of fields is entered. When uncoupled point masses are desired input only the first pair of fields. When a coupled mass matrix is requested the submatrix added has M on the diagonal, and -M on the off-diagonal. The element is not checked for internal constraints, which is the user's

(Previously, one had to reference the EPT and explicitly design END A and END B). The implementation of this new capability was incomplete in that it does not change the DVPREL2 invoked designed properties at END B. As a consequence, sensitivities of END B responses are most likely incorrect. If an optimization task in undertaken with END B responses, the redesigned structure will provide incorrect analysis results at END B and lead to invalid designs.

Aeroelastic Analysis - SPLINEi, SUPORT - Incorrect Unrestrained Hinge Moments The unrestrained hinge moments are in error in static aeroelastic analysis if the aerodynamic and structural model coupling splines the displacements from the suport points to the aerodynamic mesh. This error is caused by omitting the suport point displacements from the computation of the aerodynamic mesh displacements for aeroelastic feedback.

Nonlinear Analysis - Inaccurate Stresses using Drucker-Prager Yield Criterion The Mohr-Coulomb and Drucker-Prager yield criteria (selected on the MATS1 entry) entry create an inaccurate solution. The error is the result of an incorrect correction factor to the yield stress, which accounts for effects of the internal friction angle. Incorrect factors underestimate the yield stresses, resulting in premature yielding in tension. Avoidance: There is no avoidance, but the error is negligible if the strain is very small.

Nonlinear Analysis - QUAD4 - Plastic In-Plane Bending, Wrong Answers If a nonlinear analysis is performed with QUAD4 elements with elastic, perfectly plastic material and the elements are loaded in pure shear and twise (no bending, no axial load), then the results may incorrectly indicate that the model can sustain increasing loads even after the elements in the critical load path have reached the inplane shear plastic limit. This problem only occurs for coarse meshes subjected to pure shear loads. It is not likely to affect real world models.

Aeroelastic Anaysis - Multiple Double Lattice Groups yield Wrong Answers If a doublet lattice model (CAERO1 and/or CAERO2) is created in SOL 144 for use in static aeroelasticity, and the model has more than one interference group, the downwashes representing unit perturbations of the control devices (the DJX matrix) are incorrect under most circumstances. The problem is caused due to the erroneous introduction in Version 70.5 of an assumption that the coordinate system ID and the CAEROi ID are in the same order. This is true for a single interference group, but not for multiple groups. As a result, the wrong coordinate system may be used in the computation of the downwash. Avoidance: There is no avoidance other than to convert the model to have a single interference group. Note, also, that unsteady aerodynamics (SOL 145 and SOL 146) are NOT affected.

This will occur when the degree of freedom internal number associated with the grid/components defined on the USET entry is less than the number of grid points in the bulk data. External grid identification numbers and printed matrix values are correct. Only the component code identifiers may be displayed differently. The identifier (whichever one is displayed) is correct.

Parameter MAXRATIO is used by the DCMP module in statics analysis to control the degree of near-singularity that is allowed when computing solutions. It is input to the DCMP module with a user parameter. This parameter is not an input to the eigensolver, the READ module, although READ makes tests based on its value. If the DCMP module has not run first the value READ uses is set to 1.E7. If DCMP has run prior to READ the value input by the user for DCMP is also used for READ. Avoidance: DCMP is called in modal analysis when SUPORTs exist, when superelement reduction is used, when residual vectors are computed, and for several other reasons.

Optimization/Design Sensitivity - Senstivities of PBEAMLs that include warping may be incorrec Sensitivities of warping coefficients are ignored in the design of PBEAML section types. The effect of this is that warping coefficients are unchanged from their initial value thereby creating wrong answers when these effects are significant.
Description
Avoidance: An awkward avoidance is to design equivalent PBEAM properties using DVPREL1 and DVPREL2 entries. The SA and SB points on the CBEAM entry must be grid points for warping sensitivities to be calculated correctly even when the PBEAM entry is used. Otherwise, it is suggested that if the PBEAML is used, the final PBEAML design be submitted in a new run to see if the neglected warping effects are significant.

For nonlinear static analysis with thermal load, all intermediate data recovery of stress and strain is not correcrt to "LINEAR" elements.

A projection is made between the diameter of a CWELD element and its associated shell elements to keep the symetrical connection between the weld and the shell elements. The procedure is implemented by MODGM2 and carried out in the IFP stage. As the diameter of a CWELD element is designed during the optimization phase, the projection of the CWELD needs be updated. Secondly, if the grid locations of shell elements are designed, the projection of weld and shell elements also needs to be updated during the design cycle. Therefore, the modgm2 module should be included in the design cycle.

There are cases where some modal frequencies of an unconstrained and prestressed structure should be zero. These should occur when the forces remain in equilibrium after virtual displacement, which means the loads rotate with the model.

Optimization/Design Sensitivity - Multiple Boudary Conditions not robust with multipl analysis types Mutiple boundary conditions with frequency response analysis was introduced into SOL 200 in Version 2004.0.3 (a.k.a. 2004R2). Testing has shown problems when there are multiple disciplines as well as multiple boundary conditions. In particular, runs with ANALYSIS = MODES and ANALYSIS= MFREQ with different boundary condition can produce fatal messages. Quality report 1-1655901 is related. Avoidance: The dmap changes required to support analysis =MFREQ and analysis=MODES and multiple boundary conditions are extensive so this capability is not considered to be operational.

Optimization/Design Sensitivity - Extra responses in formatted sensitivity prints Generalized mass and stiffness responses are "spawned" when the Rayleigh Quotient approach is applied to eigenvalue sensitivity analysis. These response are typically suppressed when formatted design senstivities are printed, but they appear if two different subcases share a DRES[1 id with type = eign or freq and the sensitivity is computed for both. In this case, the senstivities of the generalized matrices can appear following the eigenvalue sensitivities. Avoidance: An avoidance is to not share a DRESP1 ID for multiple subcases.

Description
*** SYSTEM FATAL MESSAGE 6144 (PARTN1) THE SIZES OF THE INPUT MATRICES AND PARTITIONING VECTORS ARE INCOMPATIBLE. SPECIFICALLY: The number of columns in PUXLRPV is not equal to the number of rows in the column partitioning vector PVPR User Information: Size of input matrix and partitioning vectors: PUXLRPV : Rows= 2 by Cols= 9 PVPR : Rows= 11 An attachment contains a version of the AEMR.dmap that traps the missing mass matrix. Note: This same error can occur if the PARAM, WTMASS is set to zero or 0.0. It is the same effect as not having mass. This error may be slightly more prevalent in Flight Loads. The reason being is the ability to use equations on some of the flight loads forms is not available. An example would be for the Forward Swept Wing airplane. The direction say to use feet instead of inches for acceleration. So instead of WTMASS being 1/386 or the common .00259, one should be able to enter `1/32.14`. In regular Patran this is acceptable, and will return 0.031081. Flight Loads just writes .0

Miscellaneous - MEM - 'Unable to allocate /XNSTRN/ Open Core (memory) on Windows XP MSC.Nastran requires that contiguous memory be allocated. MSC.Nastran requires dlls be loaded and these dlls use open core. The various Windows o/s may allocate the required open core differently causing more or less memory to be available for nastran. Windows XP has been found to allocate the memory in such a way that only 1100mb of contiguous space is left for nastran. MSC.Nastran V2005 dummys out unneeded FLEXlm dlls and this allows more memory to be allocated. Thus, this problem is considered partially addressed in Version 2005. MSC will continue to investigate more efficient ways to allocate memory.
Description Note that it is a limitation of all Windows based operating systems that other applications that are executing will impact the amount of open core that can be allocated. MSC.Nastran V2005 has been further enhanced to improve dll management to maximize the available open core. Currently, it appears that MSC.Nastran can now access approximately 1.8GB of open core on all versions of Windows XP. Known Error

Postprocessing - MPC data in GEOM4 datablock created by module MAKEOLD is not in single precision If the model contains MPC entries, and the MAKEOLD module is used to convert the MPC entries in the GEOM4 datablock to single precision, the conversion does not take place. This happens for instance when PARAM,POST,-1 or -2 are requested and PARAM,OGEOM,YES (default) is used. The error was reported because IDEAS was terminating when reading an op2 file created using PARAM,POST,-2. In addition to being corrected in the 2005r2 release, this error was corrected in a special build of 2004.5.1 on AIX, IRIX, and Sunos only.

The alter deletes the erroneous MPC data from the GEOM4 datablock so it does not get written to the op2 file. An alter is also available that converts the double precision MPC data to single precision using the table insert functions of the PARAML module to create a single precision MPC data record which is then added to the GEOM4 datablock after MAKEOLD processing.

Eigenvalue Analysis - EIGRL, MAXSET - Nan values in Eigenvalue Table on Nec SX6 For most real world problems the NEC SX6 system's architecture is such that it realizes a performance gain when MAXSET on the EIGRL entry is set to 15 rather than the default value of 7 used on most other machines. For small problems, nastran will automatically lower the MAXSET value. One small test problem has been found that contained two static subcases (STATSUB) followed by two eigenvalue analysis where the value was lowered to 8 and it should have been lowered to 7. This resulted in Nan's being printed in the Eigenvalue summary table. Avoidance: If this problem is encountered, manually set the MAXSET value to one lower than what is reported for "BLOCK SIZE USED". Solving the eigenvalues for the two sucases in separate runs also avoided the problem. This problem has been corrected in 2005.0.1 delivered on the 2005 R1a cd.

Matrix Methods - DECOMP - PARAM,ASING,-1 DCMP, ERR flag In an analysis which has null columns in the stiffness matrix (plane strain for example) where the null columns are retained in the L-set, the DCMP module will cope with these null columns by placing 1.0 on the leading diagonal of the null columns. This behavior is controlled in subDMAP SEKRRS (for SOL 101) by the DECOMP parameter which is forced to a value of 16 if user parameter ASING is left at its default value of 0.
Description
However, if PARAM,ASING,-1 is set the DECOMP parameter retains the value -1, and the action taken in DCMP is the standard action of replacing every zero term on the leading diagonal with 1E-10. Normally (when the zero terms on the leading diagonal are not also part of a null column) this would set the ERR parameter to -1 on exit from the DCMP module and the DMAP would trap this and issue a UFM. However, starting from Version 2004.5, the ERR parameter is not set to -1 when the zero leading diagonal term comes from a null column. The consequence is that any loads applied to singular dofs generate large displacements (if ASING is set to -1) and displacements equal to the value of the applied load (if ASING is left at 0).

Remark 6 of the QRG CQUAD4 and CTRIA3 description is in error. For CQUAD4 and CTRIA3 with offset (due to ZOFFS and/or unsymmetric plies and/or z0 defined on PCOMP or PCOMPG) the differential stiffness is incorrect. Hence solutions with the need for differential stiffness (dynamic analysis with prestress, linear and nonlinear buckling) will produce incorrect results. However solutions with nonlinear geometric behavior (param,lgdisp,1) will produce correct results when the solution has converged. Please note that QUADR and TRIAR with offset will give incorrect results in any case.

SOL 600 - Loads in SOL 600 subcase get incorrectly applied
Description
For SOL 600, If the same load is applied in two subcases you must use PARAM,MRDISCMB,1 At the request of Marc development, this parameter was introduced together with an algorithm to combine distributed loads with the same magnitudes. This algorithm fails in problems where just one distributed load of the same magnitude is applied in two subsequent load cases. The default for PARAM,MRDISCMB will be changed to zero for such loadings. The avoidance is to apply slightly different distributed loads. It is unlikely likely that In a practical problem with many loads of varying magnitude that this problem will be encountered.

Matrix Methods - CASI Solver, TET10, TEMP(LOAD) - Incorrect stresses CASI solver temperature loads When TET10 elements are present in the input file, the default behavior of the casi solver is to use the "implicit" formulation for the element. This means that the element stiffness matrix is formulated internally by the casi software. The nastran generated stiffness matrices are not used for the TET10s. This is usually acceptable, unless the applied loads are element-based, as in this case, where temperature loads are used. Furthermore, in this case, in order to achieve stress-free thermal expansion, it is essential that the element stiffness and loads be compatible. Implicit element formulation should not be used. This can be achieved by placing a PARAM,ITOPTX,4032 entry in the bulk data section. Avoidance: insert PARAM,ITOPTX,4032 in the bulk data section to prevent

SOL 600 - NLAUTO - Loads not translated correctly.
Description
This example has the final time specified using NLAUTO. For SOL 600 dynamics problems, the fianl time is goverened by a combination of TSTEPNL and TABLED1 entries, any final time specified by NLAUTO is ignored. This also applies to the intial time step. For SOL 600 dyanmics, most other entries specified on NLAUTO are used with the exception of NRECYC, IDTAB, DAMP, IDMPFLG adn IPHYS. For statics, the initial time step and final time from NLAUTO overrides that provided by NLPARM. The QRG will be revised to clarify this situation. For the attachments provided, using the MD R3 released version, the Marc input decks correctly reflect the philosophy used in SOL 600 - E Dickerson 7/11/2008 Patran 2006 created a SOL 600 input deck that contains NLAUTO and TSTEPNL cards that span the same time. Whent the job is submitted, the point load is not properly translated into the MARC input deck. It only has a point load list that are numerical zeroes. It does not creat the second list showing the full load. Avoidance: NLAUTO should not be used. Manually changing the number of increments in the TSTEPNL from 100 to 101, the MARC deck is translated with both lists of point loads.

Cyclic Symmetry - Memory errors with SOL 115 (Cyclic Normal Modes) Memory error with a SOL 115 (Cyclic Normal Modes) simulation when using MSC.Nastran 2007; the same model runs okay using MSC.Nastran 2005r3. The MSC.Nastran 2007 Release Guide indicates changes were made to "Improved Selection of Reordering Methods". The Release Guide also indicates "If the default method fails, the program will attempt to use another hybrid method (for example, if BEND fails, the program tries METIS).", however in this case it appears the default case is failing but another method is not being attempted.

Default setting of radiation enclosure calculations may add heat to system.
Description
Due to inaccuracies, the default setting of view factor calculation in an opened enclosure may result in energy loss (sum of view factors < 1.0) or energy gain (sum of view factors > 1.0) in the system. In most conditions, the radiation will be lost to space because the sum of view factors is less than 1.0; however, there exists some cases that the heat is added to the system because the sum of view factors is greater than 1.0. To achieve accurate results, the user may specify NASTRAN SYSTEM(87)=3 to scale back the sum of view factor to 1.0 so that all radiation energy will be conserved.

Known Error
CR 1-56870064 THE INITIAL TEMPERATURE. The problem is that a high initial guess for temperature causes nonconvergence and for this model (with a variable cooling load & radiation as the primary method of heat transfer) a very close initial guess is necessary for convergence (use TEMPD = 60). During the solution iteration (DIAG, 51) it is found that the “NEW DISPLACEMENT VECTOR― provides temperature below zero degrees absolute which is physically impossible. RECOMMENDATION: 1) For simulations involving radiation or if the TABS value is set do not allow the temperatures to fall below zero degrees absolute during the solution/iteration phase (as this is physically impossible) and issue a warning message indicating the iteration temperatures are being reset to zero degrees absolute (based on the TABS value) for any values below zero degrees absolute. If radiation is not present or the TABS value is not set allow temperatures below zero as users may not be modeling in absolute temperature scale. 2) If radiation is present in a simulation issue a warning message if the TABS value is not set. Indicate that the temperatures are assumed to be in absolute scale (Kelvin or Rankin).

Module cmpzpr uses system cell 93 (NPCOMP) to store the number of PCOMP/PCOMPG bulk data entries.. In general, this is not a problem for list superelements. However, for part superelements, it is possible that each part has its own NPCOMP.

The PFMODE case control command requests modal participation factor output (MPF). The format of the command allows for specification of either STRUCTURE or FLUID. The STRUCTURE option produces structural MPF output using structural natural frequencies. The FLUID option produces acoustic MPF output using structural natural frequencies for acoustic structure MPF and fluid natural frequncies for acoustic fluid and panel MPF. For both cases, the STRUCTMP keyword is used to define the number of structural modes that are used during MPF calculations. When both PFMODE(STRUCTURE...) and PFMODE(FLUID...) are present in the input case control, the STRUCTMP keyword is not interpreted according to the QRG description. Rather, the value used in the structure MPF computations is the maximum of the STRUCTMP keyword values supplied in the two commands.

RIGID=LAGRANGE in sol 101 produces no mpc forces
Description
When RIGID=LAGRANGE is set in a sol 101 run and mpc forces are requested, no mpc forces are calculated. A sample deck, test_mpc_forces.bdf, is provided to duplicate the problem. test_mpc_forces.bdf includes requests for mpcforces=all and rigid=lagrange and it produces no mpc force output in the .f06. The MAXIMUM MPCFORCES output also is all zero. If you take the RIGID=LAGRANGE card out of test_mpc_forces.bdf, then mpc forces are calculated properly. The only current work around is to pull the mpc force data from the gpforce output.

Licensing - MSC_LICENSE_DISCRETE - Double Feature Checkout, UFM 3060 Setting the variable MSC_LICENSE_DISCRETE is necessary for correct license processing when two license servers, one with concurrent and one with Masterkey or EALU tokens, is used. An error exists in license processing when the MSC_LICENSE_DISCRETE variable is set that may result in a double checkout of the same feature. The error only occurs when the features on the first server are concurrent, i.e. not Masterkey or EALU, and the license check for the feature exists in multiple places in the code. Although all products make use of MSC_LICENSE_DISCRETE, only nastran tends to check for the same feature in multiple locations, so it is much more likely to encounter the problem. A second problem may result in a failed license checkout when a license feature does not exist at all on the first server but does on the second.

For rotating blades, the drill projection for shell elements must be set to “Full Projection.― 2. Boundary_Prescribed_motion card of LS-DYNA (SPCD2 card of MD Nastran) If the dof of boundary prescribed motion card in ls-dyna is not set, the dof is free (?). For example, the blade base also rotates at y-axis with gap from the rotation center. Then, the DOF of SPCD2 card must be set to 10 (z/x degrees-of-freedom for node rotating about the y-axis at location (OFFSET1,OFFSET2) in the zxplane, point (z,x). Radial motion is NOT permitted. Not applicable to rigid bodies) However, 6 (y-rotational degree-of-freedom) of DOF also needs additionally. Because 10 can make the rotation of points but, the points are fixed on y-axis rotation. +++++ When running a prestress (PRESTRS) simulation with composite shell elements the resultant initial stress information (ISTRSSH) written to the .nastin file has errors. See below for details. Some of the items in the ISTRSSH option are known to be wrong based upon the LS-Dyna documentation, however some options are not documented so the status is not known. However, it is known that using the default .nastin file on a rotating composite shell simulation causes it to diverge early in the simulation while removing the ISTRSSH history variables allows the simulation to complete. Notes on results: • Significant stress/strain oscillations are present in both cases (reference CR ). However, these oscillations worse for the case that includes the default .nastin file • Negative “internal energy― is indicated in the .d3hsp files for both cases, (again this is significantly worse for the case that includes the default .nastin file)

Performance - Windows Vista 64, Server 2008 Vista 64 and Server 2008 64 have removed a system tuning parameter that controls memory usage. Without this option, when memory usage approaches 100 percent, I/O intensive applications, especially those such as Nastran that generate very large data files overwhelm the system cache, to the point that there is no physical memory left and the machine will appear to hang.
Description
Avoidance: The work-around is to tell the various I/O intensive applications to bypass the use of system caching for their very large files. This is done by specifying the FILE_FLAG_NO_BUFFERING option in the FlagsAndAttributes argument specified for CreateFile when the file is opened. For MSC.Nastran and MD Nastran, the files for which this bypass is necessary are the SCRATCH and SCR300 files. In nastran this is accomplished by specifying RAW=YES as a SYS keyword for the appropriate files. Note that RAW=YES also requires that BUFFIO be requested instead of the default of MAPIO=YES.) Unfortunately, through a documentation oversight, the use of RAW=YES for Windows is not

SOL 400 - Fails in in SDR2 after divergence
Description
When a divergent condition is detected, SOL 400 always packs the final iteration resuts for output and post-processing before leaving the NLSOLV module. However, in some cases, such as when a job fails because of material divergence, it may leave NLSOLV without saving all required data. In this case, the job will fail later in the SDR2 module. .

The orientation vector and the offset system x-axis are then used to define the z and y axes of the offset system.," do not make it clear to the user the rule for using the orientation vector and a vector in the direction from Grid A to Grid B.
Description
It is recommended that the following be added to both remarks. A vector is formed from a cross product of a vector going from Grid A to Grid B and the oriention vector to create the offset coordinate z-direction. To obtain a nonzero cross product the orientation vector must not be parallel to both vectors from Grid A to Grid B for the offset coordinate system and End A and End B for the element coordinate system.

SOL 106 HOT2COLD, error with "ANALYSIS=MODES" in 2nd subcase (wrong answers). If a modal analysis is performed as the 2nd subcase (with the 1st subcase using "ANALYSIS=HOT2COLD") the differential stiffness (stress stiffening / follower force effects) effects are included. However according to the documentation the "ANALYSIS=HOT2COLD" subcase should only "reset" the geometry (grids), and the 2nd subcase should not include any loading history, differential stiffness, ...
Description
Reference: MSC Nsstran QRG, "ANALYSIS" Case Control option, note 8. In SOL 106, ANALYSIS=HOT2COLD allows the user to input the ‘stressed’ or deformed geometry (normal bulk data input) and ‘unload’ the structure to determine the unstressed shape. The specified load will be reversed to calculate the displacement of the ‘unloaded’ structure. This feature will also ‘reset’ the geometry to the ‘unstressed’ position for additional subcases. For example: SUBCASE 1 $ UNLOAD STRUCTURE ANALYSIS=HOT2COLD LOAD= 100 NLPARM= 100 SUBCASE 2 $ NORMAL MODES UNLOADED STRUCTURE ANALYSIS= MODES METHOD= 100 DISP=ALL ... Subcase 1 unloads the model and subcase 2 calculates the modes of the ‘undeformed’ structure; the differential stiffness and follower force effects will not be included.

The best way to insure this is to select a method like "ITER-1" or "PNT". The "AUTO" method is likely to geve poor results for the ensuing perturbation analusis.

Description
In SOL400, where RIGID=LINEAR is used, the PARAM is ignored. But, if you change to RIGID=LAGR (which is the default in SOL400), then the job will solve... this is because the lagrangian formulation of the rigid elements doesn't put the dependent DOF into the MSET, but into the LM set, which remains in the solution set.
