Seismic wavefield simulation by a modified finite element method with a perfectly matched layer absorbing boundary

The finite element method is a very important tool for modeling seismic wave propagation in complex media, but it usually consumes a large amount of memory which significantly decreases computational efficiency when solving large-scale seismic problems. Here, a modified finite element method (MFEM)...
