| Abstract: | Multi-quadric(MQ)interpolation is a new numerical method to solve partial differential equations(PDEs).The purpose of this paper is to discuss the effectiveness of the method applied to simulate groundwater flow,and the influence of shape parameters,support domain,node spacing on results.The MQ method is applied to obtain the numerical solution of three cases of 2D steady groundwater flow.The case I was a flow in a confined aquifer with constant coefficient of transmissivity(T),while Case II was with T vary... |
