I'm trying to solve a conjugate heat transfer case for a shell and tube heat exchanger, i have created my own geometry of the exchanger and created the mesh and I guess its correct till that point. I m using 4 processors to run a parallel simulation using the chtMultiRegionFoam solver.

I used the "mpirun -np 4 chtMultiRegionFoam -parallel" command to run the simulation.

I m getting this error message as shown below by i have the file in the required location in constant also i copied the polyMesh folder for all the regions in the 0/<region-name>/ folder as well for each region shell, solid and tube.

Create time

Create fluid mesh for region shell for time = 0

MPI_ABORT was invoked on rank 1 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 will add my case file in this link below

I don't understand where I'm doing wrong.
I'm doing this project to learn OPENFOAM - any help will be grateful .
Thanks for the help.
