View Animation of Particles Moving with Fluid?

Dear all,

I simulated particle-fluid flow in a pipe using CFDEMcoupling. I have obtained the animation of particle field and the animation of fluid filed respectively with paraview.
Now I am trying to view the motion of particles together with the motion of fluid. I have tried "snap to timesteps", "sequence" and "real time" modes in "view- animation view" menu, but I found the particles and the fluid can not move simultaneously.
I saved the particle data every 1000 DEM time steps and fluid data every 100 CFD time steps. CFD time step size equals 10*DEM time step size.
Could you guys tell me what how to make the the particles and the fluid move simultaneously using paraview.
Many thanks.
