The problem I encounter is the sudden increase of Umax above 0.8. Any hints on how to deal with such issue? Really appreciate your cooperation, June 20, 2023 at 6:00 pm #7532 janParticipant Dear Henderson, Unfortunately, I don’t know your setup. However, I believe that the Δt and contact forces may be too large, which could cause problems like this.
