In this talk, we introduce the so-called inverse Lax-Wendroff (ILW) boundary treatment for finite difference approximations on the Cartesian mesh. As the domain boundary may intersect with the grid in...

Irregular grid finite-difference techniques lead to equations similar to those obtained using finite-element techniques. The simpler finite-difference equations offer the advantage of greater computat...

The finite-element scheme requires more computational expense because it is time-implicit and because it requires a smaller time step than the finite-difference scheme. Simulations of normal mode osci...
