Dear experts,


Short description of my case:
Flow in rotating axial turbomachinery (somewhen in the future fluid structure interaction), the case is restricted to one passage (inlet, rotorregion, statorregion)

My proceeding so far:
I built the outer geometry (inlet, outlet, hub, shroud, walls) with blockMesh in three blocks, have a look at the attached picture.

I have the blades (one rotor blade, one stator blade) in .stl format and want to insert them in the rotorblock and the statorblock. Up till now I just worked with the rotorblade.

Next step would be meshing with snappyHexMesh. As far as I have understood, sHM cannot handle several blocks, so the faces from inletblock and stator block are deleted after sHM. The second picture shows how it looks now.


From here on I'm not sure how to proceed. I've read in severeal threads that the problem with sHM and the multiple regions can be solved with a stl file for each reagion. So I would export from my CAD program
- inlet_geometry.stl
- rotor_geometry.stl
- stator_geometry.stl
Then I can place my stl blades in the regions.

But:
How can I then implement such features as cyclicGgi and mixingPlane if my geometry ist not build with blockMesh?


I would be very grateful for some guidance!
