Hello,

I'm using pointwise to generate a 3-D Gmsh structured grid. Think of this grid as two cuboids of different size (one of size 300X300X10, the other of size 300X300X140) with one common face. I want to do two things -

1. This common face needs to have a label associated with it. (say "interface").

2. This face, even though it is a member of both blocks should be written to the mesh file only once, so the full mesh is 300X300X150.

I have tried creating the mesh through extrusion and through creating blocks out of domains but I can't seem to accomplish the goals above. I get a bunch of "unspecified" labels in msh file if I click on "include connections" and my total mesh also ends up becoming 300X300X151, presumably because the internal interface is being included once for each block.

Can someone help me with is?

Thank you!
