The Unsymmetric Lanczos Reduction (ULR) method is developed to solve the ΓΏnite-element-based solution to the contaminant transport problem. The method sometimes su ers from breakdown when at some step division by a pivot which is zero or near zero, causes numerical instability. In this paper, the Ma

The Unsymmetric Lanczos Reduction method has been recently developed to reduce the size of a large-scale linear system which is the discretized form of a time-dependent partial di erential equation problem with a large physical domain. This has been applied to solve the time-dependent advection-disp
Using either a ΓΏnite element or ΓΏnite-di erence method to solve radionuclide waste transport problems involving advection, dispersion, decay and transformation simultaneously is numerically complicated. Most applications have used only one-dimensional transport and extending this approach to higher-
In this paper we are concerned with the application of the unsynunetnc two sided Lanczos method to systems of first order differential equations and its associated problems; namely generalized eigenproblems and linear systems of equations. The unsymmetric Lanczos method is first used to generate two
