Coupling particle_input.dat into the model resulted in a very slow simulation process, and I don’t know how to solve it. I think a part of the particles may have gone out and exceeded the reactor wall, resulting in ghost cells. I tried to change the spring coefficient, but it reported an error. May I ask if everyone has any solutions.
The simulation runs longer and longer, and I have encountered this kind of thing many times, but I am not sure about the specific reason and how to modify it.

I see a lot of modified .f files in your source directory. What is the purpose of these modifications? Have you tried running with the unmodified solver code?
Attempting to run your case (with MFiX 24.1.1) I get this error after 30 seconds of running:

This is a fatal error. A particle output file (vtp) will be written to assist debugging
