Dear openFOAM users!
I am working with OpenFOAM for 4 months now. I implemented some new code in the interfoam solver. The additional code is running on a single processor but now I want to run some cases in parallel. However the test case stops during the first time step. I tried to figure out where the problem is and I could isolate the code part where the solver stopped:


forAll(gamma, cellI)
{
if (gamma[cellI]<0.01 || interfaceIdent[cellI]==1.0)
{
tempVG = tempVG + mesh.V([cellI];
cG = cG + concentration[cellI];
}
else
{
tempVL = tempVL + mesh.V([cellI];
cL = cL + concentration[cellI];
}
}

tempVL and tempVG are scalars,
cL and CG are dimensionedScalars, all initialised with zero.
I also tried with the += "sign" and it did not work either.
It would be great if someone could help me or give me a hint where I could look about it in the code.
Thank you very much!

mpirun was unable to cleanly terminate the daemons for this job. Returned value Timeout instead of ORTE_SUCCESS.

Has anyone an idea what it means?
Thank you!
