Description
Summary
The SolveLinearSystem module is used to solve the linear system Ax=b, where A is a given Matrix, b is a given right-hand-side vector, and the user wants to find the solution vector x.
Detailed Description
We support several different iteratve solution techniques within SCIRun, including Jacobi, Conjugate Gradient, and Biconjugate Gradient.
As the module iteratively approaches the solution, a graphical user interface depicts the norm of the residual. This feedback allows the user to visually confirm whether a solution is converging, and if so how quickly. It also provides a convenient interface for specifying a convergrence threshold, as the user can interactively raise of lower the maximum acceptable error tolerance in real-time. As the solver is converging, the module can send out the current guess at the solution and continue to iterate; this intermediate result is passed downstream to dependent modules, and can be useful for visualizing how a system is physically converging.
