I need to manually change particle positions during a run but if I move the particle to another processor, MFiX is not able to locate the particle. What is the best way to resolve this?
MFIX assumes that particles only move from process to another via shared boundaries. Specifically, as a particle nears a process boundary, a ghost particle is created on the adjacent process. Once the particle center cross onto the domain of the adjacent process, ownership changes; the original particle becomes a ghost and the copy becomes ‘real’.
MFIX doesn’t have built in functions to do what you want. You would have to add it in via UDFs.
