Mesh Quality Investigation to Improve Convergence Property of ICCG Method for Finite Element Method

摘要

In finite element analysis, it is commonly expected to obtain an accurate result with short time. The computation time is consumed dominantly in solving a system of linear equations. Therefore, in order to solve it with short time, an optimal acceleration factor of ICCG method and a smoothing process to improve the convergence property of the ICCG method are expected. In this paper, we have investigated a correlation of mesh quality and computation time in order to develop a new smoothing method.
