[Paraview] Gradient of 2D velocity field with paraview

[Eleonora Piersanti]

 Thank you for the answer.I think that the dimension of the .vtk file was too big. You can download the .vtk file from:
https://www.dropbox.com/s/o1wjo2brsaeu5ag/stability_realEigU_up0.vtk.tar.gz?dl=0

In which sense should I use the Slice filter? Sorry but I am quite new with paraview.Kind regards,Eleonora       Il Venerdì 30 Gennaio 2015 11:16, Eleonora Piersanti <eleonorapiersanti at yahoo.it> ha scritto:

 Your description is a bit vague to diagnose the issue. Can you share your data set? I was able to use the Wavelet source, use the Slice filter and then use the Gradient of Unstructured Data Set without any issues. Can you see if that works for you?

Regards,
Andy

Hi to everyone!I computed with finite elements a 2D velocity field. I plotted without any problem the velocity field with paraview. I would like to compute the gradient. 
I tried Filters->Gradient of Unstructured Data Set but without succes.Can you help me?Thanks, 
Nora
