Hello
I hope someone can find my error - I am having an unusual and not very descriptive fail in my simple LED light bar simulation. After 10 or 11mins I get:
mpirun noticed that process rank 2 with PID 163 on node c359ab465f04 exited on signal 11 (Segmentation fault).
The contacts and mesh have all run fine with a variety of settings, and I tried an alternate solver, so I assume it is a boundary condition error, I just haven’t managed to find it.
Thanks in advance
Peter
CFD Squad, could you see what’s wrong with Peter’s simulation?
In the meanwhile I investigate this issue to see if that’s not a bug.
Best,
Jousef
Might have found it - I was running the CFD/Hex mesh as the solid heat transfer problem is trivial and am more interested in the air side, in all but the very simplest solid and lowest mesh density it failed. Switching to a standard mesh seems to have none of these problems, which suggests it is a big of some kind.
Thanks, Peter
Oh thanks Peter for getting back on that!
You are indeed correct! Sometimes tweaking the mesh a bit (by making it finer) can have tremendous impacts on that issue and sometimes even resolve the problem.
All the best!
