A Study of Multiresolution Mesh Modeling for Finite Element Analysis

Abstract

In this paper, a new mesh combining method for supporting efficient CAE is proposed. Our method consists of three steps: 1) searching the elements on the surfaces shared with different meshes, 2) inserting elements for connecting two surfaces of the input meshes, and 3) mesh simplification for the inserted elements in order to obtain conforming mesh at the shared surface. This mesh combining method is applicable to the meshes that have no–coincident elements and geometries on the surfaces to be shared, and it is reversible. This allows us to support some operations for executing CAE, such as mesh generation of the assembly models and analysis condition setting for the meshes.
