Having FEniCS correctly installed, initialize your shell environment for FEniCS (depends on a type of installation) and type something like $ cd /path/to/FEniCS/share/dolfin/demo/documented/navier-stokes/python $ python demo_navier-stokes.py and enjoy! Some demos are extensively documented http://fenicsproject.org/documentation/dolfin/dev/python/demo/index.html http://fenicsproject.org/documentation/dolfin/1.2.0/python/demo/index.html Jan > (meshing, boundary conditions ...)
