How to fill Room and duct assembly


I am working on project where I need to supply air from duct inlet to Room through duct slots and simulate results using simscale.

Here, I prepared draft assembly in solidworks and imported to
simscale but I don’t know how to fill air as a material in assembly like this.

Please consider attached IGS File.

I really appreciate you time and looking forward to all possible solutions.


simply subtract the pipe via cut operation from the room. now you end up with a single solid. export this solid as step or iges format. simscale will show you this geometry as single solid. where ever you want the air should release from the slots into room, split these slots from the surface of pipe/duct before exporting the geometry. finally assign the air to single solid. now assign the circular pipe diameter as wall and assign the mass flow rate or velocity inlet to the slots.
