Hi!<br>I have to create an animation(movie) from turbulent flow dataset urgently! I would really appreciate your help.<br>I have a VTK_RECTILINEAR_GRID turbulent fluid flow dataset with velocity (vector) and pressure (scalar). I want to create vorticity isosurfaces. I know vorticity is curl of velocity vector,
i.e. del 'cross product' V, where del is vector gradient operator and V is velocity vector. How do I calculate vorticity from velocity in paraview? I searched a lot in filters, however, could not find a vector gradient operator. The gradient filter of paraview finds imageGradient and not vector gradient. When I applied calc and got a component of velocity (which should supposedly be treated as scalar), even then gradient was not enabled as an applicable filter.
<br>Thanks in advance for your help.<br>Aditya<br>
