EXCSTRCHK

This command creates a list of node numbers that are shared by excavation and structural parts of the model. The nodes along the perimeter of the structure and excavation interface are then removed form this list. If there are any nodes still in the list the

The structure and excavation of an embedded model should be connected (by springs or shared nodes) along the perimeter of excavation. The interior of the structure and excavation should be constructed with coincident nodes with distinct nodes numbers for the structure and excavation. Any node reported by this command may cause incorrect simulation results.
