nodal-dg-extension

A simple extension for the discontinuous Galerkin code nodal-dg by Jan S. Hesthaven and Tim Warburton.

Description

This library includes extensions to the original nodal-dg code. So far, these extensions include:

• High-order continuous Galerkin (CG/FEM) method on triangular meshes using the nodal-dg datastructures
• DG method for the high-contrast Poisson problem
• IPDG method for linear elasticity in 2D
• Routines for generating a nested dissection for the structured elimination of the resulting matrices
• Plotting routines designed to visualize the results
• Test routines designed to check behaviour under h- and p-refinement

Setup

The code needs the original nodal-dg code which can be found here: nodal-dg To run the codes, simply include both the original nodal-dg folder and the nodal-dg-extension folder in the Matlab path.
