A non-balanced staggered-grid finite-difference scheme for the first-order elastic wave-equation modeling
Wenquan Liang, Yanfei Wang, Ursula Iturrarán-Viveros
We introduce an efficient and accurate staggered-grid finite-difference (SGFD) method to solve the two-dimensional elastic wave equation. We use a coupled first-order stress-veloci…

A new efficient staggered grid finite difference scheme for elastic wave equation modeling
Wenquan Liang, Chaofan Wu, Yanfei Wang +2
Staggered grid finite difference scheme is widely used for the first order elastic wave equation, which constitutes the basis for least-squares reverse time migration and full wave…
