Hi,

I have a simple cubic box. On the top surface of the box, I have several inlet holes. And, on the opposite side of the cubic box (bottom surface), I also have identical inlet holes (same sizes located at the relative positions). I can easily mesh the top surface. How can I use this mesh and propagate toward the bottom surface? Cooper scheme does not seem to work becasue the un-meshed source surface needs to be ONE complete surface (in my case, I have the main surface + the inlet holes). Any suggestion will be highly appreciated.

Create cilinders from top holes to bottom holes. Split cube with cilinders. All volumes can now be coopered.
