Numerical Methods for Stiff Ordinary and Elliptic Partial Differential Equations.
Abstract
A semi-direct method for the fast solution of the fast solution of Poisson's equation on general two-dimensional regions is proposed. It is based on a constant-coefficient, partially consistent finite difference approximation of the Laplacian which generates a preconditioner for the conjugate gradient method. It appears to be competitive with similar methods which are among the fastest of this type. - A variety of results are given for the convergence of the wavefront relaxation merhod in large scale circuit analysis. -Analytic results for the semiconductor device equations describing the one-dimensional MOS capacitor are given, using asymptotic expansion techniques for singularly perturbed problems.
