An algorithm for stabilizing hybridizable discontinuous Galerkin methods for nonlinear elasticity

Results in Applied Mathematics, 2019
It is now a well known fact that hybridizable discontinuous Galerkin for nonlinear elasticity may not converge to the exact solution if their inter-element jumps are not properly penalized or, equivalently, if the values of their stabilization function ...

A locally field-aligned discontinuous Galerkin method

, 2018
Motivated by problems in plasma physics, we deduce several models in two- and three-dimensional geometries and construct a discontinuous Galerkin (DG) method using a non-conforming locally field-aligned mesh. This approach allows us to distribute resolution parallel and perpendicular to the magnetic field.
