** ERROR 301250 ** Unable to make a boundary temperature contact for node %7d.
The solver extracts all the nodes that lie on the part/overmolded component interface so that temperature boundary conditions can be applied to them. In this case the solver was unable to create the contact properly.
Check to make sure the node is on the interface between the part/overmolded component and that if it is connected to tetrahedrons that the tetrahedrons are indeed wall elements.
