ABAQUS Keeps crashing

ABAQUS Keeps crashing

ABAQUS Keeps crashing

(OP)
I've been working on this specific models for several weeks now and I have to do little modifications on a specific part. Every time I do a little modification, I received an error message that in the assembly the regeneration failed. When I launch the analysis, ABAQUS crashes. I then reopen it, and launch the analysis and everything goes smooth.

Any idea of what's happening and how to solve it? Never had this problem before

THank you

RE: ABAQUS Keeps crashing

Failed regeneration error means that some features of your model couldn’t have been updated after the changes you made. For example if you applied a reference point to some point belonging to the geometry and now this point doesn’t exist anymore (due to chamges in geometry) then this RP will fail to regenerate. Try to remove such features or replace them with correct ones before running the analysis. Search for them in the model tree, they will be marked with red exclamation mark.

Ok thank you. Do you think that's what makes the model crashing everytime?

RE: ABAQUS Keeps crashing

Crashes shouldn’t occur at all but I think that what causes them in this case is that there are unresolved feature regeneration issues. Possibly also model size may influence it.

RE: ABAQUS Keeps crashing

Try saving the .cae file with a new name. This enforce a reorganization of the database. Maybe that solves the problem.

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
