A robust discontinuous Galerkin scheme on anisotropic meshes
A/Prof. Takuya TSUCHIYA
Ehime University

In the talk, I will explain the standard Symmetric Interior Penalty Discontinuous Galerkin (SIP-DG) method is not robust on anisotropic meshes. I propose a new scheme with a modified penalty term and show that the new proposed SIP-DG scheme is robust on anisotropic meshes.
