Dear all,

I have compiled Foam Extend 4.1 on manjaro. When testing the installation it was complaining about not finding the MPI_ARCH_PATH. This was due to it not finding libmpi.so.1. My system has mpi.so in the /usr/lib directory. So What I did was copied the mpi.so and renamed it to libmpi.so.1. Then it was able to pass the installation test. I ran both pitzdaily and motorbike and they ran perfectly.

However upon further investigation, I noticed they didn't run in parallel. So I edited the simplefoam motorbike allrun script and added in two lines:

runApplication decomposePar
runApplication mpirun -np 6 simpleFoam -parallel
runApplication reconstructPar

And it did run, I was able to visualize in Paraview after creating a temporary .foam file.

However looking at the log I saw this:

mpirun noticed that process rank 3 with PID 260739 on node manjaro-vmware exited on signal 11 (Segmentation fault).

I wonder if I have misconfigured mpi?

Thanks

Edit 1: It seems like foam-extend cannot link system mpi correctly or is incompatible with the OpenMPI 10 and even MPICH supplied in Manjaro. Attempting to built using MPICH given in ThirdParty.

Edit 2: Decided to use Foam Extend 4.0 and that worked with SYSTEMMPI. No issues when using mpirun to solve for motorbike.
