Dear Foamer,

I have the mesh of a hilly terrain (very similar to the tutorial of moveDynamicMesh). The mesh is composed by the following boundaries:

• north
• south
• east
• west
• top
• ground

I want to extract from "ground" a sub-patch named "hill". To do this, I am thinking about using createPatch, but I need a faceSet with ONLY patch faces, and this is very problematic. My strategy was to use toposet like this:

• create a cellSet with boxToCell. The box enclosed the faces that will be part of "hill" (easy)
• create a faceSet with cellToFace (easy)

From this faceSet, I have to remove the internal faces. How can I do that?

Or is there a better option?

Cheers,
Marcel
