Creating 3D Boundary Layer like in naca_boundary_layer_3d.py
I'm trying to create a 3D Boundary Layer like in your example(naca_boundary_layer_3d.py) but my geometry (an aircraft) is more complex. When I run the example and print "bnd" in line 118 I thought it would return a list of all lines which are the boundaries to all the "top" surfaces but "bnd" just contains 4 lines: (bnd = [(1, 53), (1, 75), (1, 97), (1, 119)]). Why is that?
When I use my aircraft "bnd" contains a lot more lines and I get the error "Error: Curve loop 1 is wrong" because I try to connect a lot of random lines to a curve loop. My Aircraft is an imported BRep.
Is "bnd" supposed to just contain all lines which lay in the symmetry-plane to create the hole or all boundary-lines?
