How you run the analysis using the Patran Analysis application forms varies tremendously depending on which analysis module or preference you select, and the type of analysis you will run. Shown below are three different scenarios for an analysis with MSC Nastran. Each scenario illustrates how you would submit the analysis based on different solution types and load cases.
To submit a single load case, linear static analysis job to MSC Nastran:
1. Click the Apply button on the Analysis application form.
Appropriate defaults and selections will be made automatically.
To select other solution types or multiple load cases, you will need to access one or more lower-level subforms.
To complete a multiple load case, linear static analysis:
1. Open the Subcase Select form and select subcases with the same names as the user-defined load case names for inclusion in the job.
To change a parameter for a subcase, such as an output request, you must access the Subcase Create form, select a subcase, and bring up the appropriate form to make changes (such as Output Request).
2. Select the Apply button.
To select a different solution type from linear static,:
1. Bring up the Solution Type form and make the appropriate selection.
You may then access a lower-level Solution Parameters form from the Solution Type form to change parameters that affect the overall analysis. Subcases are created automatically for each defined load case. You can select these on the Subcase Select form or modify them on the Subcase Create form. The terms load case and subcase are interchangeable.
2. Click on the Apply button
.Monitoring the Analysis
If you are running an analysis with the MSC Nastran application module, the standard default method of receiving updates as to how the analysis is progressing is from a separate command window. Should any problems arise during the analysis, a red-flagged error message appears in the history area and a separate window with the diagnostic message appears on your screen. Once the analysis is complete, you will be notified in this area.
In order to see this command window on Windows platforms it is necessary to start Patran using the “-stdout” flag. On UNIX, the invoking window should have these messages dumped to it as it is the output for standard output. If nothing appears in this window, most likely the P3_TRANS.INI file is not configured correctly. Consult the Patran Installation and Operations Guide for more information.
Another mechanism to monitor the analysis is to use the Patran Analysis Manager application which requires separate installation and configuration.
