SibLin: A Linear Solver for Matrices with a Band Structure

3D Poisson/Diffusion/Heat Transfer Equation Solver. Licensed to Spectrian, Sunnyvale, California, Nortel, Ottawa, and Waterloo Hydrogeologic Inc., Canada Canada.

SibLin is a linear solver for matrices arising in 2D and 3D finite difference solutions of various partial differential equations such as the Poisson equation, the Heat Transfer equation, the Diffusion-Drift equation etc. The method is based on the BiCGSTAB algorithm by H. Van der Vorst and solves both symmetric and non-symmetric matrices. The source code is available in C, Fortran and Pascal.
