Vehicle CAD Model Meshing

B Bru

I am about to attempt to mesh a car that was designed in Solidworks. I plan on exporting the vehicle CAD files as .stl.

My questions:

1) There are many parts that are under the body of the car and do not need to be included in the analysis. Should I just suppress these, or when I when I use pro-surf can I just select the surfaces I want to be included in the surface mesh?

2) The body is made of panels that DO NOT form a continous surface. They have design clearances in them so they fit together easy. The clearance is about 1mm between the panels. How is pro-surf going to handle this? Can they be stitched together for the analysis? It seems like this kind of discontinuity probably will cause issues unless there is a built in way to deal with them up front.

Thanks in advance to anybody who replys!
