SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution.
Swiginac is a symbolic mathematics module for Python. It is an interface to GiNaC built with SWIG. A lot (but not all yet) of the GiNaC classes are exposed, and virtually all of the GiNaC tests pass.
The finite element package SyFi is a C++ library built on top of the symbolic math library GiNaC. The name SyFi stands for Symbolic Finite Elements. The package provides polygonal domains, polynomial spaces, and degrees of freedom as symbolic expressions that are easily manipulated. This makes it easy to define finite elements.
Symia is a minimalist C++ library for performing symbolic calculus.
TBCI is a C++ library which provides classes for Vectors, Matrices, etc., and defines operations on them such as additions, multiplications, etc.
The Boost Libraries
Generic Graph Component Library: general purpose, generic C++ library for graph data structures and graph algorithms
The Gerris Flow Solver
Gerris is a tool for generic numerical simulations of flows, possibly in geometrically complex geometries and including adaptive, multiphase and interfacial flows capabilities. Gerris can solve the time-dependent Euler, Stokes, and Navier-Stokes equations of fluid motion. The domain geometry can be arbitrarily complex. An octree mesh is used. Read more
