- Create joints within the global model which will coincide with the joints and boundary conditions of the local model.
- Analyze the global model to obtain displacements and rotations at these boundary joints.
- Develop the local model using shell objects. For each global-model joint which will coordinate with a local-model boundary, create multiple joints (L1, L2, ..., Ln) in the local model.
- For each group of joints at a local-model boundary, create a dummy joint (G) in the same location, then assign a body constraint to joint G and L1 through Ln.
- Assign restraints (U1, U2, U3, R1, R2, and R3) to joint G, then assign displacements obtained from the global model to joint G through Assign > Joint Loads > Displacements.
- Analyze the local model for the applied displacement loads. As an alternative, forces may be applied to joint G locations, though supports must be modeled.
