I'm trying to model internal fluid flow of a DC fan in a box. I downloaded the CAD model, cleaned it up to have less than 300 faces, and I created a box around it to pump air into, When I try to extract the volume, I see that it is not considering a subpart of it at all in the final enclosed volume.
This is the result on Preview Inside Faces. The central rotor is not in red, which it should have been. I have selected the outer edge loops of the box for the enclosed region.
I checked the geometry of the rotor and it said that it doesn't have any errors. Also I want the fan seperate so that I can use it as a rotating mesh.
Is this some limitation of the student version? I don't get any warnings on save.
PS, I have attached the file
