Hello, I am having trouble to make parts show up in my simulation after meshing.
My FSAE team used to use the poly meshing and we model a radiator as a Porous Region and a Fan as a momentum source. At that time everything worked correctly. But we changed to trimmed mesher in order to achieve higher mesh quality. The problem is that when we changed the mesher type, the radiador, the fan and its appendices suddenly disappear.

This is my geometry preparation and meshing workflow. When I execute the subtract everything show up. But when I execute the surface meshing, the radiator fan and etc disappear. One interesting thing that I've noticed is that every new part I try to add to the simulation disappers after meshing, unless it is touching the car main geometry. This is so strange and I hope someone can help me!
