The numerical modeling of the magnetotelluric (MT) method is of great importance for geophysics, since this method can be applied for several purposes, for example it can be used to study the crust of the earth as well as it can contribute to oil and gas exploration. For this reason, several researches have been carried out in recent decades to further develop MT. One of the major advantages of magnetotelluric is its relatively easy modeling, because in this technique the source is a plane wave. Existem varias ferramentas numericas que podem ser usadas para modelar o MT, There are several numerical tools that can be used to model the MT, among which stands out the nite element method (FEM). In this work the eciency of the isoparametric MEF for 2D modeling of the MT will be tested, whose main characteristic is the accomplishment of a transformation, with the purpose of mapping a distorted element to a coordinate system (natural coordinates ξ and η) where it becomes regular.
