Adaptive finite-element modeling using unstructured grids: The 2D magnetotelluric example

  title={Adaptive finite-element modeling using unstructured grids: The 2D magnetotelluric example},
  author={Kerry Key and C. Wei\ss},
Existing numerical modeling techniques commonly used for electromagnetic !EM" exploration are bound by the limitations of approximating complex structures using a rectangular grid. A more flexible tool is the adaptive finite-element !FE" method using unstructured grids. Composed of irregular triangles, an unstructured grid can readily conform to complicated structural boundaries. To ensure numerical accuracy, adaptive refinement using an a posteriori error estimator is performed iteratively to… CONTINUE READING
