Tony,
Im not able to run it in parallel on OF7.
So i decide to use OF7 (with CfMesh) to mesh my case and then switch to
OF8 and calculate it :).
Thank you for your help and best regards

That means your case directory is mostly OK. Exactly what command did
you use to run the executable. By serial mode I actually meant a single
processor. For example
simpleFoam
But then its surprising if it uses multiple cores. But it may be using
multithreading by default.
On a multic
Hey Tony,
it works without the -parallel flag, all four cpu's are at 100% and
running fine.

I did not see the whole email chain before. The problem is not that it
cannot find the MPI directories. I think this INIT error comes when the
program cannot start for some reason. For example a missing input file.
Does the serial version work.

I compared the /etc/bashrc files of both versions of OF (v7 and v8) and
i dont found any difference.
Here are the lines (i thought related to openmpi) of both files:
OpenFOAM v7:
Line 86 till 89:
#- MPI implementation:
# WM_MPLIB = SYSTEMOPENMPI | OPENMPI | SYSTEMMPI | MPICH | MPICH-GM |
HPM
Probably because OF cannot find your mpi installation. Once you set your
OF environment, where is it looking for mpicc? Note the OF environment
overrides your .bashrc once you source the OF bashrc. That takes its
settings from the src/etc directory in the OF source code.

Thank you for this hint. I installed OpenFOAM v8 (the newest) on my
computer and it works ...
At the Version v7 i get still this mpi error
I dont know why ...
I wish you a healthy start into the new year :)

Have you tried reinstalling OpenFOAM? If you are mostly working in a
desktop, there are pre-compiled versions available:

If you are using a pre-compiled version, do also consider reporting the
error to the packager. It seems unlikely to be an MPI error, more likel
Good morning,
im trying to fix this error by myself and i have a little update.
The ompi version i use is the:
Code:
kai@Kai-Desktop:~/Dokumente$ mpirun --version
mpirun (Open MPI) 4.0.3
If i create a *.c file, with the following content:
Code:
#include
#include
int main(int argc, char** arg
