Introduction

This MATLAB package helps discretizing the acoustic wave equation. The package builds on the sbplib repository and is used in the laplacian_curvilinear code that reproduces all figures in Almquist, M., Dunham, E. M, Non-stiff boundary and interface penalties for narrow-stencil finite difference approximations of the Laplacian on curvilinear multiblock grids. J. Comput. Phys, 2020. doi: 10.1016/j.jcp.2020.109294.
