Non-synchronous movement of grid and particle (cfdemSolverIB)

Submitted by Jak on Mon, 06/25/2018 - 15:18

Hi,

I simulated the GlowinskiMPI tutorial and my question is about the in the post-process visualization with paraview.

The cfdemSolverIB-solver creates a dynamically refined grid around the particles.
Unfortunately the grid doesn't move synchronously with the particles in the post-process. Here is the problem in a video:

Is there an easy fix to make the grid and particle move together? This would make it look much nicer in an animation...

Best regards,
Jakob

Hi Jakob,

The problem is in visualization with ParaView. You must use "Time shift scale" filter in order to visualize DEM and CFD data synchronously.

Thanks Alexander,

it works fine.

Just a note for other people, who face the same problem: the name of the filter is "Temporal Shift Scale".
It has to be applied on the controlDict.foam and doesn't work on the glyph representation of particles.
(At least I didn't manage to apply it on the glyphs with success...)
