When I try to run an unsteady flow simulation in a 2D model, I am getting an error message after the goemetric preprocessor finishes. I tried searching for this specific error message but I couldn’t find anything. I also double checked for language and date settings, everything is set correctly.

Has anyone encountered this error message in the past ?

It looks like you are using 30minute time steps which is very large. If you have a large flow it is too much flow to push each step to each cell and therefore the software is crashing. You need to reduce the time step considerably until it becomes stable. usually seconds.
