Accuracy evaluation of three-dimensional FE analysis based on nonconforming voxel element

Abstract

Purpose

Three-dimensional (3D) mesh generation for shape optimizations needs long computational time. This makes it difficult to perform 3D shape optimizations. The purpose of this paper is to present a new meshing method with light computational cost for 3D shape optimizations.

Design/methodology/approach

This paper presents a new meshing method on the basis of nonconforming voxel finite element method. The 3D mesh generation is performed with light computational cost keeping the computational accuracy.

Findings

It is shown that the computational cost for 3D mesh generation can be reduced without deteriorating numerical accuracy in the FE analysis. It is reported the performance of the present method.

Originality/value

The validity of the nonconforming voxel elements is tested to apply it to the optimization of 3D optimizations.
