What open source tool can be recommended for solving 2D instationary Navier Stokes equations (in simple geometries, but with high Reynolds numbers)? Most packages I found, I'm not very lucky with. OpenFOAM seems to be very powerful, but I think it would take some time to learn using it. FEniCS has a Navier Stokes demo, but only for the stationary case and I'm not sure if it will work for large Reynolds number. Are there any other good options? In the best case, I would like not to write new code, but just provide the geometry, boundy conditions, and data for the initial timestep.
