bulb keel sailboat
 

Hello.

I need to reform a keel and the bulb of a sailboat. I would like to use a CFD to get the best hydrodynamic accuracy. Do you know a free CFD to download?. I am complete new in the CFD, I have the points of all the surfaces in autocad but also could make them in maxsurf o rhino, so could be interesting one CFD compatible with one or more of these programms.

Thank you very much.
