Discontinuous Galerkin Galerkin Differences for the Wave Equation in Second-Order Form

SIAM Journal on Scientific Computing, 2021
Discontinuous Galerkin difference (GD) methods for the wave equation with variable wave speeds in 1D and 2D are introduced and analyzed. Contrary to prior GD methods, the proposed schemes are based on the use of interpolants on a dual grid leading to discontinuous basis functions.
