Combining finite element and finite difference methods for isotropic elastic wave simulations in an energy-conserving manner
Longfei Gao, David Keyes
We consider numerical simulation of the isotropic elastic wave equations arising from seismic applications with non-trivial land topography. The more flexible finite element method…

SBP-SAT finite difference discretization of acoustic wave equations on staggered block-wise uniform grids
Longfei Gao, David C. Del Rey Fernandez, Mark Carpenter +1
We consider the numerical simulation of the acoustic wave equations arising from seismic applications, for which staggered grid finite difference methods are popular choices due to…
