Dear Friends
I have been working on MPPIC solver(which I have developed extensively) and it works fine when I do single processor run, it works fine;

MPPICFoamFarzadd

but when I want to do multi-processor run, it fails;

echo "Mesh decomposition"
decomposePar

echo "Running"
mpirun -np 8 MPPICFoamFarzadd -parallel

and decomposeParDict is written below;

numberOfSubdomains 8;

method          scotch;

hierarchicalCoeffs
{
    n               (2 2 2);
    delta           0.001;
    order           xyz;
}

And code gives me this error;

Selecting stochastic collision model none
Selecting surface film model none
Selecting U integration scheme Euler
rhoTrans_ i = 0
rhoTrans_ i = 1
Selecting packing model none
Selecting damping model relaxation
Selecting time scale model nonEquilibrium

Selecting turbulence model type RAS
Selecting RAS turbulence model kEpsilon

    RASModel        kEpsilon;
    turbulence      on;
    printCoeffs     on;
    Cmu             0.09;
    C1              1.44;
    C2              1.92;
    C3              0;
    sigmak          1;
    sigmaEps        1.3;
}

MPI_ABORT was invoked on rank 1 in communicator MPI COMMUNICATOR 3 SPLIT FROM 0 
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 really do not know why single processor works, but multi-processor does not work. Do you have any idea?


Thanks,
