[OpenFOAM.org] SnappyHexMesh with MPICH

mpanch13114 · February 5, 2018, 07:07

Hi,
I compiled OpenFOAM using MPICH. All applications like interFoam, icoFoam, were compiled without any trouble. But, I did not find SnappyHexMesh under platforms directory. I recompiled snappyhexmesh using wmake, I understand that it is not at all compiling. Have anyone tried OpenFOAM-5.x with MPICH flag and compiled snappyhexmesh?

I found the solution myself. It was an error with MPI flag of scotch and ptscotch. I have compiled MPICH at a different location, not at the thirdparty directory. So, it tried to compile with system openmpi for snappyhexmesh. Fixed by changing $FOAM_MPI in etc/conf.sh/mpi.
