An Entropy Stable High-Order Discontinuous Galerkin Method on Cut Meshes
Christina G. Taylor, Jesse Chan
High-order entropy stable summation-by-parts (SBP) schemes are a class of robust and accurate numerical methods for hyperbolic conservation laws that are numerically stable at arbi…

An Energy Stable High-Order Cut Cell Discontinuous Galerkin Method with State Redistribution for Wave Propagation
Christina G. Taylor, Lucas C. Wilcox, Jesse Chan
Cut meshes are a type of mesh that is formed by allowing embedded boundaries to "cut" a simple underlying mesh resulting in a hybrid mesh of cut and standard elements. While cut me…
