Hi everyone!
I am simulation a case using cfdemsolverIB. but I have a problem, particles disappeared when running a certain time step.
When particle are injected at inlet, it continues move toward downstream but they interact suddenly with other particles and disappear.
Could you please help me to solve this problem?

Checking different parts
Hi,
I think you should take a look at the source code at that timsteps, specifically with these parts:
https://github.com/CFDEMproject/CFDEMcoupling-PUBLIC/blob/b23726463721d5...
https://github.com/CFDEMproject/CFDEMcoupling-PUBLIC/blob/b23726463721d5...
https://github.com/CFDEMproject/CFDEMcoupling-PUBLIC/blob/b23726463721d5...
It seems that a part of the code cannot detect the particle presence at a specific time step. It can arise from liggghts part (the first line that I mentioned above), the cell centre that is occupied by the particle (the second line) or a flaw in voidfraction calculation (in the third line). As you may know, it is just based on my guess, so It might be needed to check other parts in the source code. Hope it works for you.
Cheers,
Mo
