Thanks Gerard. The nice thing about using TVTK for the calculation (you don't need to use mayavi2 itself) is that you can use numpy arrays to generate the mesh and extract back the probed velocities. Doing the integral then should be much easier and fast as well. cheers, prabhu ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
