Hello, can someone give me a hand? I have to do a CFD analysis in Ansys Fluent of a rocket that we are going to manufacture for the student association I belong to. The problem is that the CAD file, as it is designed to be manufactured, has a lot of clearances and holes and when I import the geometry, put the enclosure and extract the geometry, as it has clearances the mesh gets into the gaps. Is there a simple way to change the CAD so that it only takes the outer surface (as if I put a cloth over the Rocket).
