Abstract
A method, apparatus, and system provide the ability to simulate dynamic motion for a computerized model (of finite mesh elements). An element diagonal lumped mass matrix of the mesh, an estimate of a highest element eigenvector and eigenvalue of the mesh, and a kinematic state of the model are computed. Processing iterates until exceeding a time duration. Incremental strain and stress tensors, and hypo-elastic material constants are computed. Within the time duration iteration, eigenvalues are converged, a power-sweep stress field is computed from the strain field using the material constants; divergence of the power-sweep stress field is computed using the current gradient operator; and a power-sweep estimate is computed. Upon convergence, the stability limit is determined and utilized as a time interval for simulating the dynamic motion.
