WaveHoltz: Iterative Solution of the Helmholtz Equation via the Wave Equation
Daniel Appelo, Fortino Garcia, Olof Runborg
A new idea for iterative solution of the Helmholtz equation is presented. We show that the iteration which we denote WaveHoltz and which filters the solution to the wave equation w…

An energy-based discontinuous Galerkin method for the wave equation with advection
Lu Zhang, Thomas Hagstrom, Daniel Appelo
An energy-based discontinuous Galerkin method for the advective wave equation is proposed and analyzed. Energy-conserving or energy-dissipating methods follow from simple, mesh-ind…
