Time compact high order difference methods for wave propagation, 2D
- 111 Downloads
In earlier papers we have constructed difference methods that are fourth-order accurate both in space and time for wave propagation problems. The analysis and numerical experiments have been limited to one-dimensional problems. In this paper we extend the construction and the analysis to two space dimensions, and present numerical experiments for acoustic problems in discontinuous media.
