Thank you for your answers guys. To give you some further insight on the application, it's about a shaft and housing system and the matrix represents the bearing stiffness. Indeed, I am trying to derive a superelement using modal reduction.  So if I understand properly I should create a dummy line element that I will convert into MATRIX27. Then I should define bonded contacts between the line element's vertices and the shaft and bearing faces. Are there any recommendations regarding the bonded contact formulation? Should I go for MPC? If yes, with what constraint type?
