Defininig contact surface's for loads in Abaqus submodeling
Defininig contact surface's for loads in Abaqus submodeling
(OP)
Dear all,
when the global model is subjected to more than one load, do we have to choose the contact surface's between global model and submodel for all loads in submodel or choosing contact surface's for one load only will define contact surface's for the other load's too?

I'm running an analysis of a disc with a central hole (global model). BC is applied around that hole. The area around that central hole and the hole itself are cut to represent the submodel so I have the BC in the same position as in global model. If I remove the BC from the previous position and place it on the surfaces where the submodel is cut from the global model then resulting stresses are much smaller from those from global model and this shouldn't happened. Please check the photos to get a clear picture of the problem. What about the two loads applied to the disc? Do I also have to mark the global model/submodel surface's connection? If so, do I have to do it for both loads or for one is enough?

So just define submodel BC* on the inner and outer faces of your submodel.
*they are different than regular BC

Just to make it clear, if I have defined the connection surface between the global model and submodel for the BC, I don't have to do it for the loads also?
