SECTION 1
Introduction ®
®
The PV Elite /CodeCalc Verification and Quality Assurance Manual provides a standard set of PV Elite/CodeCalc jobs that are used in verifying both the operation of the software and the accuracy of the result for each release of the PV Elite/CodeCalc package. The examples presented in this manual are a representative cross-section of the jobs run by Intergraph CAS. The jobs selected for this manual compare the PV Elite/CodeCalc output with results published in industry journals and with results from other software products. The PV Elite/CodeCalc output is (also) verified with hand and/or MathCad™ calculations. The component-analysis part of PV Elite, when sold separately, is called CodeCalc. CodeCalc-specific results can be found in the Software Verification section of this manual. In all other sections, the software is referred to simply as PV Elite. This manual consists of two major sections: Intergraph CAS Quality Assurance and Software Verification.
Intergraph CAS Quality Assurance describes the quality assurance procedures employed by Intergraph CAS to ensure that PV Elite is producing correct results.
Software Verification explains a series of benchmark jobs that you can use to confirm software accuracy. These jobs compare PV Elite output to published results, to output from similar software, or to hand calculations. For each job in this section, a brief description of the job and any special considerations are discussed. Following the discussion is a graphical representation of the system with selected result comparisons. Because of the volume of output, important results like required thickness, maximum allowable working pressure (MAWP), and stress are listed in tables. Users interested in the entire output can re-analyze the jobs as necessary.
The PV Elite development team is constantly testing and adding new test jobs to the QA benchmark problem set. Currently, there are more than 250 test jobs run which test thousands of different calculations. It is impractical to include all of these tests in this manual. As new Quality Assurance procedures are published, they will be incorporated into the QA methods employed by Intergraph CAS. Users with questions, comments, or suggestions are encouraged to contact Intergraph CAS to discuss future revisions to this document. User requests for new features are always welcome. By working with the user, the PV Elite development staff will continue to develop a product that best meets the demands of pressure-vessel design and analysis users.

SECTION 2
Intergraph CAS Quality Assurance Software quality assurance is generally a speculative pursuit because, no matter how much testing is performed, the next test may reveal an error in the software. The goal of any quality assurance standard is to perform enough testing to achieve such a level of confidence in the software that errors are rare and unlikely. With this objective in mind, several organizations have published guidelines for use in software quality assurance.

Software Purpose PV Elite is a package of nineteen applications that work together to design and analyze pressure vessels and heat exchangers. The purpose of the software is to provide the mechanical engineer with easy-to-use, technically sound, well-documented calculations that will expedite and simplify vessel-design and re-rating tasks. The software also provides recent, industry-accepted analyses of the designs. Calculations in PV Elite are based on the latest editions of national codes such as the ASME Boiler and Pressure Vessel Code, or other relevant industry standards that are not covered directly by ASME VIII-1, VIII-2 or other codes.
Intellectual Property Statement This manual and its contents should be considered proprietary. This material should not be copied or distributed to other parties without the expressed written consent of Intergraph CAS.

Intergraph CAS Quality Assurance
Management/Organization At Intergraph CAS, the Chief Architect, Software Engineering Manager, and Product Manager oversee the development and testing of the software product. Software development team members include: engineers, software developers, and a technical writer. All members of the development team support customers and test the software prior to each release. Specialized technical support representatives work closely with the development team. In addition, an on-staff, certified Nuclear Quality Assurance (NQA) lead auditor oversees the quality assurance program followed by the team.
PV Elite Development Intergraph CAS is wholly responsible for all software made available to the public that bears the Intergraph label on the distribution media. Changes to PV Elite are made by or with the consent of the Product Manager. Additional members of the software team include engineers, who interact at the same level and communicate directly with the product manager. Therefore, all software issues can be brought to the attention of Product Manager quickly and easily. Software engineers each bring a different kind of expertise to the team and write routines for specialized functions in the software. For example, the source code to perform structural steel checks may be written by an engineer at Intergraph CAS whose educational background permits him to do this efficiently. All members of the development staff provide customer support for PV Elite, directly or indirectly. One member of the team is tasked with quality assurance procedures for each release.
User Documentation The PV Elite user has online access to documentation spanning all facets of the software, including all of the ancillary processors and interfaces. The standard PV Elite documentation set consists of the following documents:
PV Elite User's Guide
CodeCalc User's Guide
Quick Start Guide
All of these documents can be accessed online, from the Help tab in PV Elite. The PV Elite documentation accompanies each new version of the program and is supplied in both PDF and CHM (online help) formats. Contact information for Intergraph CAS is included in these documents, as well as displayed in the help system, and in a variety of other locations in the software. We encourage users experiencing problems or confusion with the software to reference the documentation first, and then contact us for further resolution and suggestions.

Intergraph CAS Quality Assurance
Product Support Intergraph CAS welcomes input/suggestions from our users. Users having problems with our software may freely contact Intergraph CAS through our eCustomer support system, which is found on our company website. Our Technical Support staff may ask users with a numerical/computational issue in PV Elite to submit the job to Intergraph CAS. This allows our support staff to identify the problem and locate the cause, and then contact the user for resolution.
Software Issue Tracking/Resolution PV Elite supports standard practices for tracking released software issues, including:
Incorporating user feedback directly back into the development process.
Notifying users regarding hot fix or service pack updates issued throughout development
Following software release criteria based on issue review and prioritization.

SECTION 3
Software Verification This section describes the test methods through which PV Elite software team performs Quality Assurance testing on PV Elite. In addition, the section describes test methods that you can implement to validate your PV Elite program data against industry-standard benchmarks.
In This Section Test Control ................................................................................... 13 Beta Tests ...................................................................................... 14 Additional Manual Checks for Staff and Beta Users ..................... 15 PV Elite Test Jobs ......................................................................... 19 Corrective Action Standard ............................................................ 20 Post-Development Procedures ...................................................... 20 Distribution Control ........................................................................ 21 Pre-Shipping Procedures ............................................................... 21 CodeCalc QA Checks .................................................................... 23 PV Elite Sample Benchmark Problem Sets ................................... 45
Test Control Currently in the United States there is no organization that formally establishes the credibility of pressure-vessel analysis software. Therefore, software suppliers take on this responsibility. Generally, there are two ways to establish that any software product is performing correctly:
Comparing product results to hand calculations.
Comparing results to previously verified results from an external source.
If these methods compare favorably to software-generated results, then the software is assumed to be performing as expected. If the results do not compare favorably, the PV Elite development team identifies the differences and corrects the problem.
Testing Process Before a new version of PV Elite is released, the development personnel perform alpha-level testing. This involves checking the Fortran/C++ or assembler code and running of basic test problems designed to test the functionality of the feature addition, error and abort conditions, and so forth. Next, the development staff generates a series of alpha jobs that:
Test new features against existing software.
Run tests against industry standard programs, such as Compress™ and BJAC™ teams.
Suggest to customers that they independently compare the results of PV Elite against their own in-house program or spreadsheets.
Test new features against hand calculations.
Test new features against published literature, such as the ASME VIII-1, PTB-3, and other codes.
PV Elite and CodeCalc Verification and Quality Assurance Manual
13
Software Verification
Test the interaction between new features and features already existing in the software.
Once these selected alpha jobs are run and verified to the satisfaction of the lead developer, beta series testing begins. The new job results are compared to the previously verified results. Program errors that have been identified are remedied and/or justified. To summarize, at Intergraph CAS, we believe that thoroughly checking software results by hand and comparing these results to those of other software and to benchmarks assures a quality product. This method has worked very well in the past and we will check new versions using this same methodology.
Beta Tests Often before releasing the PV Elite software, we distribute the alpha-tested software to users to perform beta testing. At the end of the test period, we ask that beta users send evaluations to us, so that we can process the information, resolve any issues found, and archive feedback. The following are the beta test files for the CodeCalc module available from within PV Elite. Intergraph CAS ships some of these files with the PV Elite software. Beta Test Files Checks.cci

PV Elite Test Jobs The PV Elite QA benchmark problem set consists of over 250 different analysis jobs. Each of these jobs is run prior to release time and compared with the results from previous versions. A wide variety of jobs are checked, which includes tests of all wind and seismic codes, checks of baserings, weights, stresses, liquid pressures, MAWP, weights, volumes, required thickness and many others. By analyzing these jobs, the quality of the software is kept very high and consistent. Again, these are just a few sample problems run every time we test the software. Many of the jobs contained in this manual are listed in the table below.

Corrective Action Standard PV Elite users have many channels through which they can reach the Intergraph CAS development staff. The main way to contact us is through the eCustomer system. When a problem or error is detected, the development staff reviews the problem and takes corrective action. When a user problem is verified to be a defect, a TR (trouble report) is filled out using internal Intergraph software. After the TR is completed, the problem is fixed, and the user is notified by email through the eCustomer system. Updated PV Elite files are made available in a product Hot Fix or Service Pack, which can be downloaded from the eCustomer website. In many cases, software issues have workarounds. The Intergraph CAS technical support staff notifies users of workarounds whenever possible.
Post-Development Procedures After a new version of the software has been developed, Intergraph CAS uses the following quality assurance procedures to ensure that the new CDs are correct in content, contain the proper ESL protection schemes, and can be reproduced properly. 1. Scan the development machine for virus infection before producing any distribution set. Use the latest version of Trend Micro Office Scan virus-scanning software. 2. Assemble in a "clean" directory all of the files that comprise the installation set. This includes .EXE files, database files, and example files. 3. Run the CRCCHK program to build the CRC verification file. 4. Generate an installation program using Install Shield. Once the DVD is made, test it according to the Distribution Control procedures outlined below.

PV Elite and CodeCalc Verification and Quality Assurance Manual
Software Verification
Distribution Control To control the distribution and integrity of the program DVDs before sending them out for mass production, Intergraph CAS adheres to the following procedures: 1. After the quality assurance procedures have been completed, use the lead developer's computer to make a production copy of PV Elite. 2. Modify the installation program to load any new executables that may be released with the new version. 3. Load PV Elite onto at least one PC in the production department to check the installation program and DVD integrity. 4. Use Office Scan virus-scanning software to scan each original, all disk drives, and memory for known viruses. 5. Using the appropriate ESL, install and test the masters on another computer. All EXE files accessing the ESL must be tested. 6. Install the masters on a production computer for further use. ESL-specific files should be copied into the appropriate subdirectories for organizational purposes. 7. Send the masters to the DVD duplicator. 8. Install the software from the DVD onto each of the PCs in the engineering and development groups at Intergraph CAS. 9. Load the required set of PV Elite executables onto at least one computer in the production department. 10. Using the DVD and installation checklists, perform periodic testing of the software as necessary. The following section provides the tasks that must be performed by the development and production personnel to verify the quality of disk sets before shipment.
Pre-Shipping Procedures The following procedures help to ensure that the disk sets shipped by Intergraph CAS contain the correct product, are not infected with a virus, and are void of imperfections. 1. When DVDs are received from the duplicator, install and test a random selection from the batch. These final tests will ensure that the DVDs were correctly assembled by the duplicator, that they are not flawed, and that the ESL interaction routines are in order. The tests are software-specific and are detailed elsewhere in this manual. None of these tests should use the environment support available from the programs. Run the tests from the installation directory. Ensure that the installation directory is empty before beginning this procedure. 2. Archive a set of DVDs from the first duplication for future use and referral.

The small end available area from the shell does not match as a result of different values of tr, the minimum required thickness of cone at small end. CodeCalc calculates this value iteratively so that the cone can withstand the design pressure. With, E = 25.125 * 106 psi, A = 4.453 * 10-6, B = 5595.042, D/T = 149.191 CodeCalc computes a tr of 0.392 in., resulting in a MAWP of
which matches the design pressure of 50 psi. The ASME example uses a tr = 0.55 in., which seems incorrect.

As of this printing, ASME is in error about the stress state at point D. The stress at the point D on the short side is as per ASME Section VIII Div. 1 Appendix 13-7 Equation 29.
With, MA = -2812.68 in-lb P = 15 psi I1 = 0.0833 in4 L1 = 10 in. L2 = 20 in. R = 10 in. For the inner side, c=ci=0.5 Which gives, (Sb)Di = 5623.91 psi, while ASME has a stress value of -5583 psi.

Problem 2 - Example of Stiffening Ring Calculation This sample problem was taken from the ASME Section VIII Division 1 pressure vessel code page 531-532 A-98 addenda. This stiffening ring is a channel welded to the outside of a 169-inch OD vessel. The test here is to compute the required moment of inertia of the ring. The 4 ASME code calculated value for I’s (the required moment of inertia) 15.61 in . PV Elite obtains 4 an almost identical result of 16.2 in . The difference is due to the fact that PV Elite computes the strain factor A to more significant figures than the code example.

Problem 3 - Nozzle Reinforcement, Weld Strength, Weld Size The next sample problem was adapted from the ASME code Appendix L. This example problem tests PV Elite nozzle calculations in accordance with paragraph UG-37. This sample problem compares with ASME’s hillside nozzle example 7 Addenda 98. PV Elite automatically performs the nozzle calculation in both the hoop direction and the longitudinal direction. The results for areas required and available are in excellent agreement. This particular file applchk.pvi contains all of the ASME nozzle reinforcement calculation examples.
