The IB void fraction model leads to anomalies in the simulation of multi-spherical particles

Submitted by gang on Mon, 07/10/2023 - 15:30

I used sovlerIB to simulate a multi-sphere model. The void fraction model IB causes the particles to move crazy, and the particles will be suspended on top. However, using the bigparticle void fraction model, the simulation results are better. How to solve this problem?

CFDEMcoupling-PUBLIC does not support multi-sphere particles. This would require a couple of adjustments, e.g. for void fraction and forces to take into account the overlap of constituent spheres of a multi-sphere clump ...

Thank you very much for your reply. I noticed in CFDEM - PFM version, cfdemSolverIBContinuousForcing solver, it can simulate red blood cells. Can this solver simulate multi-sphere models?

If not, can you tell me how to implement multi-sphere simulation in CFDEM?

Thank you very much.
