Abstract
A finite-element method has been developed and analyzed for solving two dimensional conservation laws on rectangular meshes. Specially, the method is applied to the computational aeroacoustics. The method is based on a discontinuous Galerkin finite-element method in the space discretization, and a three-stage TVD (Total Variation Diminishing) Runge-Kutta method in the time marching. In this paper, we construct six independent bases on each grid element and a local limiter to ensure that the scheme satisfies the maximum principle. The method is formally third-order accurate in space and second-order accurate in time. Preliminary numerical results on scalar and system initial-boundary value problems are shown to demonstrate abilities of the numerical method.
