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