ABSTRACT
In this paper, we review a discontinuous Galerkin (DG) method and develop a finite volume (FV) method, within the framework of the heterogeneous multiscale method (HMM), for solving hyperbolic problems. Although the methods can be applied to general cases, we consider in this paper only hyperbolic scalar advection equations and Euler systems. Error estimates are given for the linear equations and numerical results are provided for the linear and nonlinear problems to demonstrate the capability of the methods.
