CFD-DEM ERROR: Unable to match particles crossing processor boundaries

#1

Hi Dear All,
I am running CFD-DEM for a liquid-solid system by DMP (mpirun -np 5). MFIX version is 19.1.0. I met this problem several times:

CFD-DEM-CrossingProcessorBoundaries_MFIX19_07162019
CFD-DEM-CrossingProcessorBoundaries_MFIX19_07162019914×440 62.7 KB

Any clues? Thank you so much.
Regards,

This usually means that there is a larger problem with your setup and particles are moving too fast.
