[Paraview] FW: vorticity

[Scott, W Alan]

When I set up my velocity vector with a calculator, I use iHat*U+jHat*V+kHat*W.  Then, after selecting streamtracers, I automatically get several new plotting parameters, including "vorticity".  Normally, vorticity is defined as Del cross Velocity_vector.  Is that what Paraview does behind the scenes?  Is this written somewhere, so I can take a look?

Thanks!

Alan
