mpirun noticed that process rank 1 with PID 56732 on node yan-virtual-machine exited on signal 11 (Segmentation fault).

wruudf,

Can you make sure that the code has been compiled correctly with mpi? for a guide on how to do this, please go to: https://github.com/su2code/SU2/wiki/Build-from-Source

Cheers,
