New developments in the finite-element method for seismic modeling (original) (raw)

Recent advancements in the finite-element method (FEM) for seismic modeling emphasize high-order accuracy through novel techniques. These developments, such as the spectral-element method, mixed FEM, and discontinuous Galerkin method, enhance computational efficiency while overcoming traditional limitations of FEM compared to finite-difference methods. This paper reviews these techniques, illustrating their application to wave-propagation problems and discussing their implications for improved seismic modeling.
