theindianlel is on a distinguished road

I am trying to do an aeroacoustic simulation in star-ccm+. To create FWH Surfaces, I created a conical surfaces enclosing my potential noise sources and deleted this conical volumes from the main fluid volume. I then created interfaces between this conical part surfaces and corresponding subtracted fluid volume surfaces. When I try to mesh, it does not generate a mesh and I get "too many intersection" errors.

What am I doing wrong here? Is there any other correct way to create an FWH- Surface?

Thank you.
