Study of Weight Functions in the Element-Free Galerkin Method

摘要

The weight function plays an important role in the performance of the Element-Free Galerkin Method (EFGM). It can impose a tremendous influence on the accuracy of solutions, the complexity of computation and the rate of convergence. The continuity of the weight function causes the continuity of the shape function in the EFGM. Therefore, it becomes particularly urgent to select an appropriate weight function suited to electromagnetic calculations.
