| Abstract: | This paper expounds the basic principles of the boundary element method, describes how to apply the boundary element method to solve the forward problem of two-dimensional magnetotelluric sounding and studies the method of copying BEM with FEM, with the purposes of producing a more realistic analysis method, offering both accuracy and cost efficiency.Theoretical analysis and modeling example show that the method of coupling BEM with FEM is able to model effectively the variation of MT field. |
