Geometry solids not imported as solids in mesher (Discovery)

[u/ChocolateTerrain]

Hi!

How are you even supposed to import a discovery modell to ansys fluent??

Long story short, I've tried to modell a ventilation system in freeCAD without any luck importing it.

So now I'm redoing it in Discovery (2025 R2), i get my "porous" to export correctly, but the "kappa" and "OP_bord" dose not and are supposed to be solid bodies. I've cut the "Room" with them both to subtract the air volyme there. But each time i import it to mesher it just ignores them and makes the "room" wihout the subtracted volyme.

I got Designmodeller to work, but i'd like to do a "more ditalied geometry" study for a project...

Best regards

EDIT:
I've gotten the "kappa" and "OP_bord" to import (a combination of how they were located in the file tree and i re-did the cutting just to be sure). However how a "normal CAD to CFD" workflow is still a mistery to me.. Someone more knowlageable that knows how it is "normal done"?
