Can anybody tell me if the NASA TetrUSS is usable for cars -- i.e. can it have a ground plane that is part of the "flow space" and not part of the model being tested?
TetrUSS: NASA Tetrahedral Unstructured Software System
It does have a Mac version, though I'm unclear about how to use the model I have made in it, to test for drag.
If not, how can I test my model in a CFD program?
