Paraview - Lid Driven Cavity
 

Hey,
I'm trying to postprocess the velocity vector results from a lid driven cavity simulation and being new to paraview im abit stuck. The two things I want to do are:

- Plot streamlines with a certain streamfunction value.
- Determine the centre of each vortex within the cavity. (ideally with some sort of automated process).

Any ideas on how to go about doing this will be muchly appreciated. Thanks in advance,
Kieran
