parallel running problem

ramsaybolton · October 8, 2018, 05:03

i am running IC Engine simulation, i am able to run my case in serial which is taking too much time, but
when i try to run it in parallel that time after say 0.1 degree of
simulation i am getting
--mpirun noticed that process rank 21 with PID 62969 on node iceng3 exited
on signal 11 (Segmentation fault).
this error.
also i am getting segmentation error if i close event in regions.
please help me with this

What is the specifications of the computer on which you are running the simulation?

socket 2
cores per socket 8

Did you check for errors in the geometry, like triangle intersections when the boundary moves in runtime.

Hi RamsayBolton,
Your case is crashing for some reason.
Check the diagnostics in Studio for the surface and ensure that any moving boundaries & events are setup correctly.

If you continue to have problems, please send you case to us by contacting support directly.
