Hello,
so im trying to run the SettlingMPI tutorial but it doesnt quite seem to work for me properly. From what i have seen from a colleague, there should only be one particle showing in paraview which is sinking over time. For me its arount 16 particles at once and im assuming that these are the same particles but at the following timesteps. That is just an assumption though and I am not 100% sure.
I have added a screenshot.
Now i would like to know wether there is acutally a way of only showing one particle at its current timestep. I cant really tell wether i accidentally made changes to the settings or wether there is a reason for this.
thank you in advance

Hi,
Hi,
It depends on how you call paraview for your case? If you call it in CFD directory, you should use paraFoam -builtin (for decomposed case) or paraFoam (for reconstructed case). Then you can only see the fluid domain in which the particles can be detected by voidFraction field. This option shows the fluid domain fileds in different timesteps. However, the DEM part generates som dump files which can be converted to vtk format by lpp.py python code. Then you can add these vtk files as a group and visualize them in different timestes.
