The Augustus Code Package
Michael L. Hall
December 4, 2006
Abstract:
The Augustus Code Package solves the P_1 Equation Set (a superset
of the Diffusion Equation Set) on unstructured multi-D meshes.
Augustus is used as a diffusion kernel in the
Spartan and Magnum
Code Packages.
The new version of Augustus is a part of the
CÆSAR Code Package.
