SibLin

Overview

SibLin is a linear solver for matrices arising in 2D and 3D finite-difference solutions of partial differential equations — the Poisson equation, the heat transfer equation, the diffusion equation and others. It's built on the BiCGSTAB algorithm by H. Van der Vorst, and solves both symmetric and non-symmetric matrices.

The SibLin graphical interface plots two-dimensional distributions of the solution at any cross-section of the three-dimensional structure. Each 2D cross-section can be reduced further to a 1D cross-section along either axis of that plane, for detailed inspection of a single trace.
