MESHLESS ALGORITHM IN TWO-DIMENSIONAL ELECTROMAGNETIC FORWARD CALCULATION
摘要
Abstract
As a new numerical computational method based on the principle of variation, the meshfree method has maintained a rapid development in recently years. It has been widely used to study the problem of mechanics and electromagnetics because of avoiding the onerous mesh generation. In this paper, two-dimensional magnetotelluric response was calculated by the meshfree method. The basis of the meshfree method was explicitly described and the particular meshless calculating formulas were deduced through the generalized var-iational principle. The program is verified by comparison with the analytic response of a symmetrical ladders model and with the finite difference results of laterally inhomogeneous model.关键词
