A Fast Update Approach of a Stiffness Matrix for a Multi-rate Finite Element Deformation Simulation

摘要

In this paper, we propose a rapid update approach of a global stiffness matrix for a binary online re-mesh and multi-rate finite element deformation simulation. Our approach enables us to generate realistic and stable reaction force and deformation with quick movement such as stick slip phenomenon. In early evaluative experiments, we can confirm that our approach contributes to the reduction of computational cost of deformation simulation.
