Error while modelling Repose Angle with JKR


I’m currently new to PFC. I’m trying to model the angle of repose while incorporating the Hertz-Mindlin model in ball-wall contact and JKR in ball-ball contact. Every time I’m trying to run the model, I keep recieving the error “An accumulated value has become greater than the maximum allowed. This is normally caused by bad property values in a constitutive model or by the model going unstable.”

Can someone explain to me how I can avoid such error?
