Calculating divergence after change the particle-particle restitution coefficient in TFM model, DT<DT_MIN divergence

Hello, everyone!
I am using mfix-21.1.4 to calculate the fluidized bed under Linux system. After the particle-particle restitution coefficient is changed from 0.97 to 0.8588772669, calculation diverged. Only changing the particle-particle restitution coefficient leads to calculation divergence. I wonder if there is any way to make the calculation converge after changing the coefficient?
Can anyone help me? I would be very grateful. Here are the relevant documents.
