Hello Kravell!
OK, I think you are right. With low speed the difference is neglectable.
(And I don't expect an iPhone App to solve all cases, otherwise the guys from Fluent etc... will lose their jobs...
).Thanks!

The App's name is "wind tunnel" so I assume the fluid is compressible, e.g. air. It there a way to simulate an incompressible fluid as well? I am interested in the different behavoir of water and air. A simple witch to make the compressibility to off would be fantastic! Thomas |

Hi, Even though the name is "wind tunnel", it simulates incompressible fluid. It is generally considered an acceptable approximation for air as long as speed is not too high, which is the case here. |
