[Paraview] Fwd: Error to calculate vorticity with ParaView

[Ana Emilia Rabelo]

hello,

I'm trying to calculate the vorticity using the filters: Compute Derivative
and Gradient of Unstructured data set, but it is not working, because when
I compare it with Tecplot the results are different. Then I was wondering
how I could calculate it and what would be the formula to calculate it
using the python calculator or the calculator filter.

Thank you,
Ana Emilia Rabelo
