摘要

Finite element method is a common method in MT forward modeling. This paper mainly studies the application of triangulation finite element method in forward modeling; The steps of forward modeling with finite element method are as follows: (1) Constructing the expression of variational formulation from the electromagnetic field differential equation; (2) Divide the solution area into several small triangle elements; (3) Using shape function to write out the matrix of functional expression corresponding to each unit; (4) Synthesize the population matrix and solve it to get the field value.
