Exporting two different meshes simultaneously from salome to openfoam

Posted March 16, 2018 at 14:13 by p@nkaj

Hello,
This is my first post.

I want to export two different meshes at a time from salome 8.3.0 to (OpenFOAM-in-Box-18.02-r638).
I don't want to compound those meshes.
I used med and cgns formats to export, but failed.
When I exported using med, I was unable to convert it into foam file. I tried using ideasUnvToFoam <File_name>.med.
The polymesh folder was created, but all the files i.e. boundary, points, faces, neighbour and owner were empty....

fms file creation

Code:

surfaceToFMS file.stl

extraction of edges from stl file

Code:

surfaceFeatureEdges file.stl file.fms -angle 30

This is to visualize with paraview

Code:

FMSToSurface -exportFeatureEdges file.fms fileEdge.fms

#several steps for improving mesh quality

Code:

cartesianMesh.exe
checkMesh.exe >> log.Mesh1
improveMeshQuality.exe
checkMesh.exe >> log.Mesh1
improveMeshQuality.exe
checkMesh.exe >> log.Mesh1
improveSymmetryPlanes.exe

Pstream has two sub directories :

I think the solution in a general c++ code using MPI would be to add a line like:
MPI_BARRIER(MPI_COMM_WORLD)
