A semi-Lagrangian discontinuous Galerkin (DG) -- local DG method for solving convection-diffusion equations
Mingchang Ding, Xiaofeng Cai, Wei Guo +1
In this paper, we propose an efficient high order semi-Lagrangian (SL) discontinuous Galerkin (DG) method for solving linear convection-diffusion equations. The method generalizes…
