Particle Pathlines filter
 

Hi all,

i'm dealing with a .vtk file, it's a turbulent channel flow. I'm trying to apply Particle Pathlines filter without success. The problem is that this filter seems not active, so i suspect that my file is not complete or i'm doing something wrong.
I've upload my data Field1.vtk here:

I'll be glad if someone give could explain me what's the real problem .

Thanks in advance
