I am trying to locate the reference information for the equations used to validate the AutoPIPE software as stated in the ATS documentation.  "THEORY: Refer to the AutoPIPE Reference Information in the AutoPIPE Online Help, for details on the equations used by AutoPIPE for calculation of stresses."

Furthermore can you send me the copies of the Mathcad's sheets showing the hand calculations for a specific model? 

Answer:

Typically, the reference equations can be found at the following AutoPIPE help section: 

Help > Contents> Contents Tab> Reference Information> Code Compliance Calculations> select the correct piping code.

The overall objective of this ATS is to provide a means of validation for the AutoPIPE computer program to analyze and produce accurate results for a variety of piping models as installed in a specific operating environment.

The accuracy of AutoPIPE is verified by Bentley during execution of Alpha Tests, which are performed prior to any Commercial or Quality Assured release. Alpha Tests consist of a matrix of test systems designed to capture key feature attributes related to numeric and functional processing. Each set of test outputs is compared to a prepared set of expected results (i.e. Mathcad's, hand calculations, some other well established computer program etc.), and evaluated for acceptance. Only those people who are part of the QA&R program have a right to access Bentley's facility in Walnut Creek, CA  for the purpose of QA audits or inspection to verify the implementation of our quality assurance program. Only during the audit can QA&R user have access to all the references mentioned above.
