[Commercial meshers] is it possible do use foamMeshtoFluent for 2D?

Jeanp · April 28, 2015, 10:56

Hi all,

I would like to know if it is possible to convert a "2D" mesh made with snappyHexMesh (extrudeMesh) into a 2D mesh for Fluent. I've tried with foamMeshToFluent but I get a 3D .msh. For me it is logic but I just want to know if it is possible and how also

Thanks!

Jean

Quick answer:

OpenFOAM mostly works with 3D meshes, therefore it's not likely that it will be able to export to Fluent's 2D msh format.
If Fluent can load another type of surface mesh, you can try using foamToSurface, for example if you run it like this:
Code:
```
foamToSurface test.msh
```
It will tell you this:
Code:
```
Unknown file extension for writing : msh
Valid types: ( ac gts inp obj off ofs smesh stl stlb tri vtk wrl x3d )
```
Since the utility fluentMeshToFoam can import 2D meshes, you could ask/hire someone to create a modified version of foamMeshToFluent to support this feature.
