FOSPACK is a package for the discretization, assembly, and solution of
systems of PDEs using a First-Order System Least-Squares (FOSLS)
formulation. The talk will briefly cover the FOSLS motivation and
methodology, the solution of the linear systems using Algebraic
Multigrid (AMG), as well as a number of features of the package,
including adaptive mesh refinement and automatic linearization
of nonlinear equations.
