Validation of a 3-D high-order discontinuous Galerkin solver with transducer boundary conditions through comparisons with the fast nearfield method
A 3-D discontinuous Galerkin (DG) solver is presented for ultrasound propagation in heterogeneous media. The formulation advances particle velocity and density perturbation fields using explicit time integration, while numerical fluxes couple elements and enforce material interfaces, enabling layered configurations and...
