An energy-based discontinuous Galerkin method for the wave equation with nonsmooth solutions
Yangxin Fu, Yan Jiang, Siyang Wang
We develop a stable and high-order accurate discontinuous Galerkin method for the second order wave equation, specifically designed to handle nonsmooth solutions. Our approach inte…
