I am running from free surface simulations using VOF, and the software keeps crashing. This is not from numerical instability. Anyone have any tips on how to keep fluent from crashing? Is it more stable outside of workbench?

Any help is much appreciated.

Broadly speaking it's the same in workbench & standalone. I personally have had less problems using fluent standalone, but this is my subject opinion.

- do you get any error messages when Fluent "crashes" ?
- what is the computational load of your process, (I have had problems with fluent crashing due to running out of memory etc in the past)

Thank you for getting back to me. Usually it doesn't give me any error message. I think the problem is with my university's license manager. I get far fewer crashes on campus than at home. As for the memory, I only run two processes, so I always have plenty of CPU and memory still available. I'll try running fluent by itself, thanks for the tip.
