Femap Neutral File Format

FEMAP Neutral File Format This Document describes the FEMAP Neutral File Format. This information is not required unless you are going to write your own interfaces to read or write Neutral Files.

A.1 File Structure FEMAP Neutral files follow a very structured format that makes them relatively easy to read and write. All data is contained in "data blocks". Each data block begins with a "-1" and an ID, and also ends with a "-1". In a formatted Neutral file it looks like the following: Description

File Contains Column Numbers .........1.........2.........3.........4 1234567890123456789012345678901234567890 -1

Start of Data Block 100 Data Block ID Data All of the data for this data block. This is usually multiple records. -1 End of Data Block Any number of data blocks can be in the file, and they can appear in any order. Data blocks of the same type can even be repeated, when necessary.

A.1.1 Formatted Neutral Files Formatted Neutral Files contain free-format, record oriented data blocks. You will notice that each value is separated by a comma, and there are even trailing commas at the end of each record (line). These commas are not required, but values must be separated by at least one or more spaces. The only fixed field requirements are for the "-1" start and end of block indicators - they must always be preceded by 3 spaces and start in the fourth column. All other records should start in the first column.

Integer Values Integer values are all subject to the limitations for the corresponding numbers in FEMAP. In no case can an ID ever exceed the range 1 to 99999999. Other limitations are described in the formats shown below.

Real Values Real numbers can be written in either floating point or exponential format. Any reasonable number of significant digits can be included, but the total length of any line can not exceed 255 characters.

Character Strings Titles and other text items are simply written as a series of characters. In a formatted file, they are always the only item in the record, so the end of the line terminates them. If the character string is really empty (has no characters), FEMAP will write the special string "". If you are reading a Neutral file, you should interpret this as a blank string.

A.1.2 Library File Formats FEMAP library files (materials, properties, report formats and views) are saved in an enhanced formatted neutral file format. This format follows these rules: 1. The first line of the file is a one-line header that identifies the file as the appropriate type of library. For example, the material library must say: FEMAP Version 5.0 Material Library

A-2

FEMAP Neutral File Format 2. Each entry in the library is preceded by a comment line that looks like: $COM

0

5.0

AISI 4340 Steel

It must start with $COM. The second field must be the entity type (i.e. for materials - 0=Isotropic, 1=2D Orthotropic...). The third field is the FEMAP version of the datablock. The remainder of the line is the entity title. 3. Following the comment is a standard FEMAP data block containing one, and only one entity. If you follow these formatting rules, a FEMAP library can be read either one entity at a time with the various Load from library options, or in its entirety with the FEMAP Neutral Read Translator.

A.2 Data Block Formats This section defines all of the data blocks that are currently used by FEMAP. The following table lists all of the supported blocks: ID 1 2 3 4 5 6 7 8 9 10 50 51 100 101 102 200 201 401 402 403 404 405 406 407 408 409 410 411 412 413 420 430 431 432 433 450 451 470

They have been superseded by another similar datablock. Since FEMAP can write Neutral files for previous versions, some of these obsolete datablocks may still be produced if you select an old version format. In that case, the datablocks are still documented. In most cases, these data blocks can still be read by FEMAP, but may be removed completely in a later release. You should never write any new interfaces that use these obsolete formats. When you look at the following tables, the record numbers refer to the line numbers relative to the start of the datablock in a formatted neutral file. You can tell the type and size of these numbers (or characters) by referring to the "Size" column.

A-4

FEMAP Neutral File Format Changes from previous versions have a version number included in the description - like (4.1+) to mean version 4.1 and later. If you find the version number change in the Record or Field column, this implies that that record or field was added in that version - files generated in previous versions will not have this data present. If the version change is listed in the Description column, this implies that the description was changed. This usually occurs when additional options or meanings are given to an existing field.

FEMAP Neutral File Format Repeated Records for all of the results values in one of two formats which can alternate depending on the entity numbering in your model. When reading the file, FEMAP reads a record and if there are only two fields it assumes it is Format 1, if there are more fields, then it must be Format 2. Format 1 entityID ID of the single node/element for results 4 byte, long integers value result value 8 byte, double precision Format 2 start_entityID First ID 4 byte, long integers end_entityID Final ID values[0..n] Values for each entity from start_entityID to end_entityID. Results for all IDs in this range are included – no holes. Values are written so there are a total of 10 fields on each line. Therefore the first line has 2 IDs and 8 values, remaining lines have 10 values (last line may be less)

Output Components The components are 20 Vector IDs of other vectors that are "components" of the current vector. There are several possible ways these components are used: 1. THE CURRENT VECTOR CONTAINS THE VECTOR MAGNITUDE OF 3 OTHER VECTORS THAT ARE THE GLOBAL X,Y, AND Z COMPONENTS OF SIMILAR DATA: In this case Components 0, 1, and 2 are the Vector IDs of the X, Y, and Z component Vectors respectively. An example of this type of usage is Vector 1 (TOTAL TRANSLATION) which has Component 0=2(X TRANSLATION), Component 1=3(Y TRANSLATION) and Component 2=4(Z TRANSLATION). These components MUST be defined for deformed/animated plotting to work correctly. Components 3 through 19 must be 0 for this case. 2. THE CURRENT VECTOR CONTAINS DATA WHICH SHOULD BE PLOTTED IN A SPECIFIC GLOBAL DIRECTION: In this case, if plotting should occur in Global X then Component 0 must equal the current Vector ID. If Global Y, then Component 1 = current Vector ID, and if Global Z then Component 2 = current Vector ID. All other Components must equal 0 (i.e. only 1 nonzero component and it is equal to the current Vector ID). 3. THE CURRENT VECTOR CONTAINS ELEMENTAL CENTROIDAL DATA FOR ELEMENTS WHICH ALSO HAVE RELATED DATA AT THE ELEMENT CORNERS: In this case, the number of nonzero components depends upon the number of nodes on this element type (for example, output for linear plates has 4 components-4 nodes/corners). The nonzero components must equal the Vector IDs of the same type of data at the corners of the elements. For example, if the current vector is 7033 (CENTROIDAL VON MISES STRESS) then component 0 may be 20133 (CORNER1 VON MISES STRESS) and component 1 may be 30133 (CORNER2 VON MISES STRESS) etc... If you do not have corner data, all components must be 0. If the components are defined, FEMAP will use the corner data (not the data in the current vector) when calculating data at nodes (like for contouring). If no components are defined, FEMAP will assign the centroidal value to each node when doing the calculation. 4. THE CURRENT VECTOR CONTAINS LINE ELEMENT DATA AT ONE END OF THE ELEMENT. This is just like the previous case. The first component is the vector ID of the End A data, the second component is the vector ID of the End B data. This type of output also requires special settings in the "comp_dir" variable. Set "comp_dir" to 2 if you want FEMAP to use the data as it is specified. Set "comp_dir" to 3 if you want FEMAP to reverse the sign of all End B data when doing a Beam Diagram. This adjusts for differences in sign conventions between the various analysis programs. 5. ALL OTHER CASES:

FEMAP Neutral File Format

A-73

All components should be 0. This will force the data in the current vector to be used for every case. The current setting of the View Option Deformed Style - Deformed Direction option, will control the Deformed plotting direction.

Output Vector IDs If you are writing your own Neutral Files, you can choose any vector IDs that you want, but the normal conventions used by FEMAP are as follows:
