A compact high order Alternating Direction Implicit method for three-dimensional acoustic wave equation with variable coefficient
TL;DR: A Pade approximation based finite difference scheme for solving the acoustic wave equation in three-dimensional heterogeneous media is proposed and is conditionally stable with a better Courant–Friedrichs–Lewy condition and theoretically proved by energy method.

An Efficient and high accuracy finite-difference scheme for the acoustic wave equation in 3D heterogeneous media
Keran Li,Wenyuan Liao +1 more
TL;DR: In this article, a compact high-order finite difference scheme was developed to solve the 3D acoustic wave equation with spatially variable acoustic velocity, and the boundary conditions for the second derivatives of spatial variables have been derived by using the equation itself and boundary condition for $u$.

A compact high order Alternating Direction Implicit method for three-dimensional acoustic wave equation with variable coefficient
TL;DR: In this paper, a Pade approximation based finite difference scheme was proposed for solving the acoustic wave equation in three-dimensional heterogeneous media. And the efficiency of the new algorithm was further improved through the Alternative Directional Implicit (ADI) method.

Da Li,Keran Li,Wenyuan Liao +2 more
TL;DR: The development and analysis of a new explicit compact high-order finite difference scheme for acoustic wave equation formulated in divergence form, which is widely used to describe seismic wave propagation through a heterogeneous media with variable media density and acoustic velocity is considered.
