Features tested

Removal of substructures on the global level is tested.

Problem description

A model is constructed of three substructures to represent an excavation process. First, a gravity load is applied to the elements, causing them to deform under their own weight. The top substructure is then removed, which causes the bottom layers to expand because of the relief in load. The middle layer is then removed, causing further expansion of the bottom layer.

Results and discussion

The results from the substructure analysis exactly match the results that are obtained when substructures are not used.
