[Gmsh] Python parallel loading

[Bernd Hahnebach]

FreeCAD uses OCCT for geometry data structure and SMESH for mesh data  
structure. Lately there has been integrated GMSH as meshing software  
for FEM meshes to be able to make conformal connected multibody meshes  
(CompSolids in speach of OCCT) with different mesh size for different  
voulems of the geometry. All tools in this regard are accesable by  
python. All data is saved inside FreeCAD and GMSH is called through a  
system call. But FreeCADs data structure itselfs may be support the  
structure you need.

BTW:
OCCT 7.1 has been released. Has someone tried to compile GMSH against  
OCCT 7.1 ?  I use 7.0 ATM.

This package clearly does not meet my needs. It's just a geometry  
creation tool which uses gmsh through a system call. It generates a  
mesh and open it using meshio (another package from the same dev)  
which does not keep physical nor partition tags. I need both.


I have a fork of MeshIO that keeps physical tags and partitions.

It doesn't use mpi4py though.

Hi,
Does anyone know of a Python mesh interface with a built-in  
distributed data structure (using mpi4py preferably) that works with  
Gmsh?
Thanks.
