[vtkusers] VTK file with ParaView

[misabel at litec.csic.es]

Hi everybody!

I am starting to use ParaView skill in order to see my results.

As an output of my code I obtain a file with extension ".vtk", I have a
velocity field and a pressure field. I can open it without any problems,
but when I want to see vector plots, this is impossible because in the
"vtk file", each variable is declared as scalars. I don't know what
exactly I have to do, any help will be welcome.

Thanks in advance
Isi
