Abstract
A model representing a physical object is received. The model contains a pilot node, one or more surface nodes, and a constraint for coupling displacements/movements of the pilot node with the one or more surface nodes via a set of constraint equations. The pilot node is subject to a condition that restricts node swapping for resolving node dependency in elimination method. An internal node is created based on the pilot node. The internal node and the pilot node occupy a same location initially. The internal node and the one or more surface nodes are constrained via the set of constraint equations. The model is modified with the internal node and a numerical spring connecting the pilot node and the internal node. The numerical spring is configured for limiting relative movements between the pilot node and the internal node. Physical behaviors of the physical object are simulated using the modified model.
