I applied two remote forces to one face and got this warning message: “Two or more remote boundary conditions are sharing a common face, edge, or vertex. This behavior can cause solver overconstraint and is not recommended, please check results carefully. You may select the offending object and/or geometry via RMB on this warning in the Messages window.” How can I resolve this warning message?

      Remote points are attached to the geometry through constraints equations (CE). This defines coupling between the dofs of the remote point and the dofs of nodes of the scoped geometry. However, each node can only be coupled once : if a node of the geometry is scoped to two or more remote points/forces, this causes overconstraint and the solver will delete one set of CE to relieve the overconstraint. Thus the warning message to inform the user. A method is to create a remote point scoped to the face first and then define the two remote forces by scoping them to the remote point.
