snappyHexMesh aborting
 
Hi all,

i am using sHM for a complex mesh generation. Here a picture of my geometry.

The error.log got that output:

Code:

--------------------------------------------------------------------------
mpirun noticed that process rank 0 with PID 3588 on node tobi exited on signal 9 (Killed).

The process.log (maybe it is helpful)
