An Open source CFD program called dolfyn aim to promote the use of numerical simulation Computational Fluid Dynamics (CFD).The project is an initiative of a Dutch province in the south of the Netherlands (Zuidoost Brabant) with financial support by the European Union.

I haven´t tested it yet . The downloads are free and can work in windows and Linux.

The Engineer Frank Lumpitzsch from the Technical University Berlin kindly offered his experiences providing a Computer Fluid dynamic analysis from the my graduation Project, the Submarine Neptuno. He analysed how much drag the submarine has underwater, if it has a tendency to go up or down when the body of the submarine is pushed foward and so on…. For my happyness the results were very good and are going to help a lot the further development of this kind of submarine.

The 60 pages of the results alog with videos are going to be available soon at the project´s page.

Thank you Frank!
