ANSYS KM# 2041347 shows how RBD commands can be used to get reaction force on a contact. However, These points are important for multiple contacts: 1. There’s only one contact allowed per body in RBD analysis. 2. For multiple contacts, slice bodies and connect with fixed body-body joints. 3. Do not place multiple bodies in the same part for connected mesh, when using a contact on each body. 4. Alternatively, one can select multiple target face locations on the same body for one contact.
