Generation method of distributed data for FEM analysis

Abstract

Many automatic mesh generation methods for the finite element method (FEM) have been reported. However, for the case of complicated heat generation, a large number of data depending on the position must be added to the mesh data. Other examples, which also need a large number of data depending on the position, are functionally gradient material and biomechanics. In these cases, it is difficult to prepare the distributed data. This paper shows that these problems can be solved by using an improved multiple-reciprocity boundary element method. In this method, contour lines of distribution are used and these distributions are assumed to satisfy the Poisson equation approximately.
