D036 A Robust Solver for CSEM Modelling on Stretched Grids W.A. Mulder* (Shell International Exploration & Production BV) SUMMARY Modelling and inversion of marine Controlled-Source Electro-Magnetic data for prospect evaluation requires a fast and robust solver. A multigrid method presented earlier provides excellent performance on equidistant and mildly stretched grids. The grid stretching takes care of the singular behaviour of the electric and magnetic field near the current source. In addition it reduces the errors due to the artificial boundaries by placing them sufficiently far away from the source and receivers. Unfortunately the performance of the multigrid method breaks down
