    • Dispersion and Dissipation Errors of Two Fully Discrete Discontinuous Galerkin Methods 

      Yang, He; Li, Fengyan; Qiu, Jianxian; 邱建贤 (SPRINGER/PLENUM PUBLISHERS, 2013)
      The dispersion and dissipation properties of numerical methods are very important in wave simulations. In this paper, such properties are analyzed for Runge-Kutta discontinuous Galerkin methods and Lax-Wendroff discontinuous ...

    • Positivity-preserving DG and central DG methods for ideal MHD equations 

      Cheng, Yue; Li, Fengyan; Qiu, Jianxian; Xu, Liwei; 邱建贤 (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2013-Apr 1)
      Ideal MHD equations arise in many applications such as astrophysical plasmas and space physics, and they consist of a system of nonlinear hyperbolic conservation laws. The exact density rho and pressure p should be ...
