Remeshing Technique for Three Dimensional Finite Element in ABAQUS

Abstract

To resolve the divergence problems in three-dimensional finite element simulation caused by the mesh distortion,put forward a three-dimensional remeshing technique in ABAQUS by making use of the good interface between ABAQUS and HYPERMESH.Simulated a rubber block compression process using this technique.The results show that:1). the grid distortion at sharp corners has been improved significantly and this remeshing technique can attain reliable results,especially in three-dimensional models with the large deformation;2). the initial analysis load capacity should be reasonably determined in order to obtain the better remeshing results.This technique can resolve the problems brought by the mesh distortion very well.
