Hello,

I'm new to OpenFoam and have a questions about the solver icoFsiFoam of OpenFoam-1.6-ext.
Until now I was able to run some FSI test cases with icoFsiFoam on one processor but as soon as I try to run the cases on 4 processors by starting the job via the mpirun command I get the following error message:

Code:
Pstream initialized with:
    floatTransfer     : 0
    nProcsSimpleSum   : 0
    commsType         : blocking
SigFpe : Enabling floating point exception trapping (FOAM_SIGFPE).

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD

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.

mpirun has exited due to process rank 0 with PID 9104 on
node itlrstud053 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

If I try to solve only the fluid part of the same case with icoFoam in parallel mode everything just works fine.

It would be great if someone could help me to run the solver in parallel mode!

Greetings

Michael

Hi

You got any solution on that? Cause I am struggling with the same error. Do not really know how to handle the solid mesh decomposition. Is it necessary?

Hey,

no I did not manage to get a solution for this problem. But with openfoam-extend-3.0 comes a new FSI solver which can run in parallel mode. The solver is called icoFsiElasticNonLinULSolidFoam maybe you can try this solver.

They even use solid mesh decomposition in the tutorial of icoFsiElasticNonLinULSolidFoam-Solver. If you don't want to use solid mesh decomposition as shown in the tutorial you have to link the fluid-processor folders directly to the solid folder.
