Dear,

I've got to make a work in which I design a car and test it in my own built windtunnel. But I do also want to test the car in the ''solidworks'' windtunnel as I want to compare drag coëfficients. So I designed the outer layers of a car in Rhino and saved it as a .STL file. When I open it in Solidworks I get to see ''there has to be at least one component for a simulation flow analysis''. I actually designed the car in T-splines for Rhino, but I converted the model to a Rhino model so it's just a rhino model right now.

I uploaded the car so you can open it in Solidworks so know what I am talking about

Thank you very much!
