Hi @Anonymous
Just to confirm,
- By "crash", does the software shutdown? Or just some error during the analysis?
- Does the problem occur with any model, such as a simple cantilever beam and a linear static analysis? Or is it related to the model or analysis type?
This article describes some problems that may be occurring: Interface crashes with a CER when analysis is started in Simulation Mechanical. One of the first 3 solutions may be the answer.
If the problem is related to the Simulation Job Manager (meaning the software crashes when you start the analysis), a short term solution to "keep you going" would be to perform the analysis from a command prompt. It's actually pretty easy with the batch file attached to the following article, once you setup a few things in the batch file. See How to run an analysis from the command prompt (DOS window) in Simulation Mechanical.
Let us know what you find out.
