A weight-adjusted discontinuous Galerkin method for wave propagation in coupled elastic-acoustic media
Kaihang Guo, Sebastian Acosta, Jesse Chan
This paper presents a high-order discontinuous Galerkin (DG) scheme for the simulation of wave propagation through coupled elastic-acoustic media. We use a first-order stress-veloc…
