Error Factors Analysis of Meshless Local Petrov-Galerkin Method for Fully Developed Magnetohydrodynamic Flow

This paper analyzes the effects of some parameters of meshless local Petrov-Galerkin method for fully developed magnetohydrodynamic flow in rectanular duct on error of numerical simulation. These parameters includes: the size of local quadrature domain , the number of local domain in local quadrature domain, and the size of support domain. By a series of numerical simulations, the optimal values for these parameters which may cause a good accuracy of computation are determined.
