The Nastran error messages refer to errors that are usually associated with the preparation of the Model Input File. Corrective action is often indicated in the message text or the explanatory information following the text. In some cases, reference may have to be made to sections of the Nastran Solver Reference Guide for correct input file formats or for clarifications of procedures. Information messages are unnumbered and usually do not require any user action. They are mostly used to output model status as the program executes, but are also useful in detecting errors in your model.
Error Message Descriptions
Module and number identify Autodesk Nastran error messages. These messages are sorted into five groups:
| Message Identification Number | Message Type |
|---|---|
| S1000-S1999 | System Messages |
| T2000-T2999 | Model Translator Messages |
| G3000-G3999 | Geometry Processor Messages |
| R4000-R4999 | Results Processor Messages |
| E5000-E5999 | Solution Processor Messages |
Error messages have the following format:
where, AXXXX is the message identification number as shown above and message is the error message text.
All error messages (S1000-E5999) are written to the Model and System Status Files. Module specific error messages (M2000-E5999) are written to the Model Results Output File. If a system error (file management, memory management, etc.) occurs, you must refer to either the Model or System Status File for the error identification number and message.
Note that information written to the System Status File is appended so the most current run may be at the end of the file. Also, the Model Status File will only be generated if the Model Initialization directive MODLSTATUS is set to BOTH or FILE.
