HI Foamers!


I am learning snappyHexMesh, trying to create mesh. But I am receiving error as:
Setting up information for layer truncation ...
--------------------------------------------------------------------------
mpirun noticed that process rank 0 with PID 0 on node bidesh exited on signal 9 (Killed).


My snappyHexMeshDict:

I was running with 3 processors.


One More problem. I have foam extend 4 and OF18 in my computer. When I run the command for snappy, I use OF18 version. I am receiving some strange things in terminal:


--> FOAM Warning :
From function void* Foam::dlOpen(const Foam::fileName&, bool)
in file POSIX.C at line 1601
dlopen error : liblduSolvers.so: cannot open shared object file: No such file or directory



Can anyone kindly help me to understand these issues.
Thank you.
