A Numerical Method for Solving the 2D Direct Problem in Magnetotellurics

Abstract

We present a numerical method for solving the bidimensional forward problmem in magnetotellurics. Maxwell's equations are treated as a system of first order partial differential equations, and first order absorbing boundary conditions are introduced to minimize undesired border effects. The approximate solution is obtained by means of a mixed hybrid domain decomposed finite element procedure. Results obtained on a parallel supercomputer IBM SP/2 at Purdue University are shown.
