Compact finite difference modeling of 2-D acoustic wave propagation

作者：

Highlights：

• A new application of mimetic fourth-order finite differences coupled to leap-frog time integration to wave propagation phenomena.

• A new 2-D compact formulation on nodal meshes with Crank–Nicolson time integration.

• A new mimetic formulation based on leap-frog scheme and Crank–Nicolson time integration on a 2-D staggered grids.

• Two new fourth-order compact finite difference schemes to model acoustic motion under homogeneous boundary conditions.
