Abstract
In this work, we implement and compare two fourth-order compact finite difference (CFD) methods to model the propagation of acoustic waves on a 1-D domain. The first scheme is based on standard implicit CFD constructed on nodal grids and must solve a couple of tridiagonal linear systems at each time iteration. The formulation of the second method uses the novel staggered mimetic CFD that explicitly approximate derivatives at cell center points. Mimetic FD operators inherit this name from the fac...
