Hello everyone!

I have a problem running a parallel simulation.

In the first steps of my case, I do the following instructions:

-surfaceFeatureExtract
-blockMesh
-refineMesh
-snappyHexMesh
-setFields
-decomposePar

I have no problem with these steps.

Then, i type: "mpirun -np 4 interFoam -parallel"

But here, the simulation encounters a problem and send the following message:

"No MRF models present

No finite volume options present

mpirun detected that one or more processes exited with non-zero status, thus causing

Does anyone knows what i do wrong?

Does the simulation runs in serial mode? Have to tried just running interFoam without decomposing the domain?

Hi denis08,

You provide very little information about your case so it is not easy to guess. However, from the top of my head I would say to run refineMesh and snappyHexMesh like is shown below in order to overwrite the existing polyMesh:

refineMesh -overwrite
snappyHexMesh -overwrite

Hello.
I am currently facing the same error. Have you found a solution for this?

Thank you.
