Crash without error message: OpenSees

Post by rsarkar » Mon Mar 18, 2019 6:33 pm


I am running a soil model (on OpenSees 2.5.0) which crashes without any error message. The model goes something like:
....<model buildup>....
....<analysis 1>....
....<model modification>....
....<analysis 2>....

When I remove all code after analysis 1, the model is successfully executed. However, when I add the second part of the code, the app crashes without any error message even before executing the first analysis.
The modifications involve removing some elements, creating new nodes equalDOF-ed with the nodes corresponding to these elements, and recreating the removed nodes with the new nodes. The old set of nodes are in a 4-dof system and the new in a 3-dof system. I have double checked, and I am not incorrectly entering any node/element IDs, connectivity or missing a fixity anywhere.
I have also tried to run the code on the 32-bit version instead of 64-bit, but the same crash occurs. Running OpenSees on a DOS terminal shows no error message whatsoever.

I would really appreciate some help with why this happens!
Thank you for your time.
