Abstract:In magnetotelluric (MT) forward modeling, the numerical algorithm and its computational structure, which are used to solve large liner equations, will impact the efficiency and accuracy of the modeling calculation. The performance of multigrid(MG) solver for frequent domain electromagnetic problem such as MT is investigated. The discretization of the governing equations is obtained by the finite element method (FEM). The MG acts as a preconditioner in the calculation, which can optimize the computational structure with different grid, further more improve the algorithms' smoothing efficiency
