A Dual Super-Element Domain Decomposition Approach for Parallel Nonlinear Finite Element Analysis

摘要: This article presents a new domain decomposition method for nonlinear finite element analysis introducing the concept of dual partition super-elements. The extends ideas from displacement frame and is ideally suited parallel static/dynamic structural systems. In method, realized by replacing one or more subdomains in “parent system,” each with placeholder super-element, where are processed separately as “child partitions,” wrapped super-element along boundary. overall system, including satisfaction equilibrium compatibility at all boundaries, through direct communication between pairs proposed has particular advantages matrix solution methods based on frontal scheme, can be readily implemented existing programs to achieve parallelization ...
