Merge adjoining cellsregions
 

Dear Foamers,

I have a submesh constructed as a fvMeshSubset from a 3D pipe geometry, figure below. The constructed mesh in this case is one cell thick to represent a 1D mesh. Since the cells in the bend are hanging loose OF sees the mesh as having several non-face-coupled regions.

Is there a way to merge the cells in the bend to obtain a single "correct" mesh to calculate on?
