[Paraview] second try -- vtk file -- scatter data -- vector field

[Diego Avesani]

Dear All,

Sorry this is my second message, I do not know if the first has been
posted. I did not received the email that confirm that my message has been
posted.
I change my mailing options so I try again.


I am a newer in paraview and I need a help, please.

this is my problem: I have random particles in a 2D domain and I would like
to plot concentration field and velocity vector field.

Thanks in advance to everyone, any help will be very important.

I am able to create a .vtk file to get the concentration field but when I
try to add the velocity field I get the following error:

ERROR: In /home/utkarsh/Kitware/superbuild/paraview/src/paraview/VTK/Filtering/vtkDemandDrivenPipeline.cxx,

This is my input file:
