(Open-source) cfd software for design use
 

Greetings!


I'm looking forward to adding a CFD tool in my industrial design toolkit. The software should be open-source (Win or Linux) and be able to read in STL (or similar) meshes. STL import is not necessary if a open-source mesher is also available. My main interest is to perform basic aerodynamics simulation, ie. digital wind tunnel testing.
