Hi
I am currently doing a project related to aircraft wings. While executing the analysis I get an error.


To run the case i had used

/usr/bin/mpirun --hostfile machines -np 8 simpleFoam -parallel

MPI_ABORT was invoked on rank 2 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

I've set up the nfs server and client and also enabled the passwordless ssh. I need help as I am new to openfoam.

Are you sure that is the right commands to run on your cluster? I.e. try instead

/usr/bin/mpirun -np 8 -machinefile machines simpleFoam -parallel

Hi
Sorry for the late reply. I had tried the code that you mentioned I got the same error as mentioned in my above post
