Abstract

Methods of and systems for executing a simulation of a constrained multi-body system. The method comprises, using a physics engine, simulating the constrained multi-body system, wherein: the constrained multi-body system comprises articulated constraints, the articulated constraints are associated with a geometric stiffness matrix; the geometric stiffness matrix defining a geometric stiffness; a diagonal approximation of the geometric stiffness matrix is generated; and the diagonal approximation is used as part of a stability analysis in which damping is automatically adjusted so that the damping stabilizes the simulation of the constrained multi-body system.
