Detailed Description

A sampledSurface from a triSurfaceMesh. It samples on the points/triangles of the triSurface.

It samples using the cell nearest to the triangle centre so does not check the cell the centre is actually in ...

In parallel every processor just operates on the part of the surface where the face centres are inside the mesh. It is then up to the caller to stitch the partial surfaces together.
