The high-order polynomial reconstruction is performed by using cell-averaged quantities based on the hierarchical orthonormal basis functions. Our method has a very local property like the discontinuous Galerkin method which facilitates parallel programming for high-order computations. The high-order accuracy in time is obtained by Runge-Kutta method. Numerical computations demonstrate the effectiveness of our method.
