HIGH ORDER STABLE MULTI-DOMAIN HYBRID RKDG AND WENO-FD METHODS被引量:1
《Journal of Computational Mathematics》2018年第4期517-541,共25页Fan Zhang Tiegang Liu Jian Cheng 
This work is partially supported under the National Natural Science Foundation of China No. 91530325, the Fundamental Research of Civil Aircraft MJ-F-2012-04, and National 973 project No.2012CB720205.
Recently, a kind of high order hybrid methods based on Runge-Kutta discontinu- ous Galerkin (RKDG) method and weighted essentially non-oscillatory finite difference (WENO-FD) scheme was proposed. Those methods are...
