Adaptive Refinement Movie

This quicktime movie shows the adaptive refinement iterations from the MARE2DCSEM code for an example offshore oil reservoir and salt body model. The movie starts by showing the initial coarse finite element grid. The next sequence of images show the finite element grid as it is adaptively refined using an adjoint weighted gradient recovery error estimator, as described in Key and Weiss (2006) and Li and Key (2007). Elements flagged for refinement are shown in green. After 21 refinement iterations the CSEM responses converged to a relative difference of less than 1%. The final image shows the CSEM responses (inline E, vertical E and crossline B) computed at an array of seafloor EM receivers.
