Hi guys, I´m revisiting this topic because I´m trying to run a CFD simulation of a car´s 3d model in VWT. I´m using 3ds Max 2016 to export the model. I tried different approaches and different softwares that are installed in my university´s facilities. These were:
First I tried exporting the 3d model into IGES, as suggested, but it seems that 3ds Max will only export to IGES from a NURBS model. So I tried to open it in Autodesk Surfacewrap, which can import .obj models and export them to NASTRAM. The geometry generated has only the rear wheels identified as separate objects but imports fine into Hyperworks VWT, but when I try to run the simulation, it lasts for only a few minutes and results as if the wind tunnel was completely empty.
How can I make this work?
