[Paraview] PV 3.10.1 computing vorticity from vector field

[Tim Gallagher]

The output from the ComputeDerivatives is Cell Data. To do those things, you want to make it Point Data with another CellDataToPointData filter.

The calculator would see it if you changed it from point data to cell data. But since you want to do other stuff with it, add the interpolation filter again and then it will appear with the rest of your point data.

Works correctly but what must I do to:
1 make a vector or contour plot
2 tracer plot or vorticity lines (like streamlines) plot?
The choice for these is only the velocity field that I read.
Calculator does not see the vorticity vector that was created.
Thanks for you help,
Stephen
