Post Processing

Hi everyone,

Can someone help me solve this problems? When I finished running the case, and using the paraview to do the postprocessing, it cann't read the velocity file? And also I am using MPI, so I would like to use reconstructPar command to combine the decomposed files, however, I also met a similar problems about which I have no ideas.
Thanks a lot

Hallo,

I recently updated my CFDEM system and also installed a new OpenFOAM-4.x version, including ParaFoam 5.0.1.

In the past I have been using Christian Richter's plugin libliggghts_reader.so. However, when I try to load this in ParaFoam 5.0.1 I get an error.

Does the plugin work with ParaFoam 5.0.1 respectively where could I download the updated version.

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

Hello All,

This is Min.

I hanged around the post-processing forum and learned that, apart from the Point Sprite plugin (which is not available in my paraview version), there is another faster approach to visualize the particles, which is Point Gaussian.

I tried both "Glyph filter" and "Point Gaussian", and I found that the particle size is not consistent???

Please refer to the uploaded screenshots for the detailed settings in Paraview when I visualize the particles using both "Glyph filter" and "Point Gaussian", then you will understand what I mean.

Dear all,

I am a beginner in LIGGGHTS

I am trying to simulate the sediment transport around the pile as posted https://www.cfdem.com/forums/simulating-erosion-and-deposition-around-pile

So, I have wondered how to compare the scour depth with experimental data.

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!!!

Dear collegues,

I installed paraview5.4.0 on an ubuntu system coming with OpenFOAM 5.x. Missing the Point Sproite tool (which I used in my former installation) I found the information that this is no longer available and one should use the Point Gaussian tool. However, the Point Gaussian tool is not available in the list of "presentation" (properties panel) and is also not available in the list of manageable plugins.

Additionally, in "/opt/paraviewopenfoam54/lib/paraview-5.4" no library containing this tool can be found.

Hi,

I am using CFDEM and run a simulation ''tutorials/cfdemPostproc/fill cylinder'' by ./Allrun.sh, but unable to visualize.

What is the procedure to visualize the coupling effect of DEM and CFD in paraview?

Thanks
Ritwik

couldn't find anything in a search

in paraview, I use the liggghts reader and the point sprite plugin to visualize my solutions, because that saves a ton of computer resources compared to using a glyph.
