hej, can I find an example ho
can I find an example how to use gmshToFoam in any of the OpenFOAM downloads?
I want to use a mesh (.msh) generated by gmsh for Navier-Stokes solver.
The openfoamwiki.net describes how to convert a gmsh gemoetry (.geo) file for OpenFOAM using gmsh2ToFoam. Is the '2' in the executable name a typo or is it different from the executable for a .msh?
Hi Guillaume You'll find tw
You'll find two example .msh files CubeVer1.msh and piece-extr-rec.msh.gz under OpenFOAM-1.4.1/applications/utilities/mesh/conversion/gmshToFoam/.
gmsh2ToFoam is a user contributed utility downloadable from wiki and made when gmshToFoam still hadn't supported .msh file format version 2.
Thank you, Takuya! I was searc
Thank you, Takuya! I was searching through the complete OpenFoam directory for *.msh files, but somehow I missed them in the obvious location.
Now I have applied gmshToFoam succesfully to the CubeVer1.msh. At least there are no error messages, only one warning.
But the CubeVer1.msh doesn't contain any patch names. How can I use it with the icoFoam/cavity example, where movingwall, front, back,... patches names are used to identify the boundary conditions?
Hi Guillaume, You have to che
You have to check which patch name (patch0, patch1, ...) is assigned to which physical surface number from the message output of gmshToFoam (the number suffixes of patch0, patch1, ... don't necessarily match the physical surface number assigned in a .msh file) during conversion and hand-edit polyMesh/boundary afterwards.
If you'd like to use information contained in $PhysicalNames section of .msh file version 2 format, as far as I know gmsh2ToFoam is the choice so far.
