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!

This was small exaple of product development collaboration:

Last year we received a beautiful carbon skateboard deck from a material research institute in the University of Clausthal in Germany. Our job was to test it and say what we think of the new board because those guys from the institute are good in making things light, but they don´t know nothing about riding boards! The riders: Nico Hopp, Lars Mayer, Simon Schlör and myself have had lots of fun helping them understanding what was good and what could be better in the board. We made a nice video that was send to the university researchers with images of the board in action together with each riders toughts. The video will be posted soon here in Lets Evo Blog.

As I was riding my bike at the Mountains close to Frankfurt I had a chance to see this amazing bike made completely Wood.

The maker of this piece of Art is the Engineer Reinhold Eichhorn who works at Braun electronics. He did the whole work buy hand at his home workshop. And you could tell that his is not playing by taking a closer look at the saddle, It hiddenly screams “No pain no game”.

We are trying to convince him to show some of his building technics used on this bike.
