Accuracy evaluation of three‐dimensional FE analysis based on nonconforming voxel element. (2014) - ,
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.
