Dear all,
Are there any easy ways to do following things for post results of pure particle flow, such as in paraview:
1) How to do temporal and spatial averaging for particle velocity? I mainly want to get the vector field like fluid flow.
2) How to track the particles in a region specified at time=0 s?
Looking forward to any suggestions. Many thanks.
Best wishes
Solient

1) vector fields: use
1) vector fields: use cfdemPostproc and maybe field average (https://www.openfoam.com/documentation/cpp-guide/html/guide-fos-field-fi...). DCS has some field mapping in LIGGGHTS-Premium as well. For distribution of e.g. velocity over width, I'd use a histogram for each saved timestep, save it and then add the bin counts.
2) Do you mean you want particle tracks? Use the TemporalParticlesToPathlines filter.
