Multi-criteria adaptation of physical simulations
Résumé
This paper presents a GPU implementation of a revisited Mass-Tensor model to dynamically adapt the simulation of deformable objects. In this model, the mechanical forces are computed at the node. This facilitates the manipulation of the elements to improve the computation performance while preserving accuracy. The study of several criteria, either geometric or mechanical, determines the most appro- priate response. For example, the adaptation involves different actions: to locally refine the object's mesh, to raise the degree of an object's element or to adapt the mechanical laws.
