Thanks, at some point we have to think about orography, but I think then we can just use the coordinates of the extruded mesh instead of the host mesh. Cheers, Eike Sent from my iPod

thanks, I guess I could also just use the code that Lawrence commented out below… I figured out what the C code does, and that’s what I’m doing now. In a radially extruded mesh, are the normals in one column always the same? I think this is what the code assumes, since it only uses the coordinates in the base cell.
Yes, the normal to the horizontal facet is always in the same direction, at least with no orography, since the horizontal facets in a column are parallel with radial extrusion
