Use of Block Factorization Iterative Methods in a Stiff ODE (Ordinary Differential Equations) Solver for Two-Dimensional Method-of-Lines Applications

摘要

A code for solving stiff systems of ordinary differential equations is modified in order to make it more suitable for solving large stiff systems where the Jacobian is a block tridiagonal matrix. Such systems often arise when the method-of-lines is used to solve two-dimensional partial differential equations. 16 refs. (ERA citation 12:032424)
