2D unstructured mesh
 
Hi!

Recently I am modeling a 2D problem using empty patches. Due to complexity of the geometry I can not use the "blockMesh" tool.

Has anybody some experience in importing 2D mesh to OpenFoam?

Previously I have used for 3D geometries, ICEM to produce unstructured mesh and FluentMeshToFoam to import it. That worked perfectly. but in 2D, there should be a single layer of elements in the third direction. I tried extruding a 2D mesh in ICEM, but then it was not possible to assign "part" name to the faces of the extruded mesh (because mesh is not a geometry object). So i had no boundaries (inlet, outlet, etc.) in OpenFoam.

Thanks!

Just import a 2D mesh into OF
 
Hi,

You can just make a 2D mesh in say GAMBIT and export it as such. When importing into OF, the mesh will be changed into a 3D mesh with an empty front and back.
