Hi
My computer has 16Gb RAM and 8 CPU cores and I can not run 3D wing optimization of my own wing. I run the Onera Wing in tutorials successfully but when I run my own case customized within Onera example, It stops with this error:

mpirun noticed that process rank 2 with PID 1063 on node 3931db16682e exited on signal 9 (Killed).

If it is memory problem, why the basic Onera example runs successfully?
My mesh file is also not very fine, and it is unstructured SnappyHexMesh.
I have attached the Log file for your consideration.

I would appreciate it if you help me in this regard
