Hello!

I have some huge problems with the following task: (see attachment)

I have to set up a wind tunnel (face 2), a smaller quader which has to act as interior for a smaller meshing setp (face 4) and an aerofoil in the middle.

My first problem is the substraction of the three faces.
Which steps i have to follow?

1. substract face 1 from face 4 (without retain or something?) gives then Face A
2. substract the new face A from face 2 (also without retain or something?

i think i have to set up face 4 as interior, right? do i have to do this after the substracting?


kind regards!
