Comparison between Meshless Finite Element Method and conventional FEA with modeling, calculation time and result

Abstract

Conventional finite element analysis （FEA） requires the selection of parts to be modeled and the simplification of the CAD shape prior to meshing, and requires a large number of man-hours. Furthermore, even at the mesh creation stage, in order to properly use 1D elements, shell elements, and solid elements, analysts with knowledge and experience of FEA needs to perform work with a large number of man-hours, which is expensive. In this study, it is shown that the time from loading CAD shapes to obtaining analysis results is dramatically reduced by the meshless method finite element analysis. The analysis results are also considered.
