How to post process the results in Paraview (i.e check the velocity)

Hello everyone,

How to post process the results in Paraview (i.e check the velocity and particle diameter)?

I using this code:

# Create imaging information #make a dump of particles and the stl file

dump dmp all custom/vtk 10000 post/movingMesh_*.vtk id type type x y z ix iy iz vx vy vz fx fy fz omegax omegay omegaz radius

dump dumpstl all mesh/stl 10000 post/dump*.stl

But unfortunately nothing is appearing in Paraview except seeing how the particles flow!!!
