# Hedge

Hybrid and Easy Discontinuous Galerkin Environment

hedge is an unstructured, high-order, parallel Discontinuous Galerkin (DG) code that I am developing as part my PhD project. hedge’s design is focused on two things: being fast and easy to use. While the need for speed dictates implementation in a low level language, these same low-level languages become quite cumbersome at a higher level of abstraction. This is where the “h” in hedge comes from; it takes a hybrid approach. While a small core is written in C++ for speed, all user-visible functionality is driven from Python.

# Features

Since everybody loves bulleted lists, here’s one for you. Hedge:

• Supports simplicial unstructured meshes in two and three dimensions (i.e. triangles and tetrahedra)
• Approximates using orthogonal polynomials of any degree you specify at runtime
• Solves your problem in parallel using MPI
• Comes with canned operator templates for
• Wave equation
• Heat equation
• Poisson equation
• Maxwell’s equations
• Makes it really simple to roll your own operators using friendly, mathematically-oriented (and dimension-independent, if desired) notation
• Visualizes your solutions in parallel with XML-based VTK or Silo files. It directly supports Paraview and Visit.
• Runs on your Nvidia CUDA-capable graphics card.
