IEFG针对矩形域内的Poisson方程的精确度研究

IEFG Method Studies about the Accuracy of Poisson Equations in the Rectangular Domain

在移动最小二乘插值法的基础上,对插值型无单元Galerkin方法(IEFG)在矩形域内的势问题的精确度进行研究.IEFG方法在运用于工程计算时,可以直接施加边界条件,具有计算简便精度高的优点.

To base on the interpolating moving least-squares method（IMLS）,the study has proposed the interpolating element-free Galerkin（IEFG）method for the two-dimensional potential problems in a rectangular region.The IEFG method,which is applied in engineering calculation,the boundary conditions can be applied directly,and the error analysis shows that the IEFG method has higher calculation precision.
