Abstract:
We describe implicit and explicit formulations of the hybridizable discontinuous Galerkin method for the acoustic wave equation based on state-of-the-art numerical software and quantify their efficiency for realistic application settings. In the explicit scheme, the trace of the acoustic pressure is computed from the solution on the two elements adjacent to the face at the old time step. Tensor product shape functions for quadrilaterals and hexahedra evaluated with sum factorization are used to...     »
