How to create internal fluid volume for CAD assembly


Hi, I am new to simscale platform!
I want to create air volume inside my assembly for the simulation. I tried simscale mentioned ‘flow volume extraction methods’ but it didn’t work for this assembly. Please let me know how should I approach this problem.

I linked my project up here, in this I want to analyse blade performance of ceiling diffuser.


Welcome @vish93tp,

Upon inspecting your geometry, I found a few intersecting bodies, which could potentially be causing this issue. Can you go back to your local CAD tool and clean up the geometry in this red-and-grey-mixed area?

Let us know if this fixes the issue or if further troubleshooting is needed :stuck_out_tongue_winking_eye:
