Factorization in Block-Triangularly Implicit Methods for Shallow Water211 Applications. Modelling, Analysis and Simulation

摘要

In this paper the authors analyzed the convergence of iterative solution methods.211u001eIn particular, the authors focused on the integration of ODE's originating from 211u001eshallow water applications, where the ODE system contains a highly stiff part 211u001ecorresponding with the horizontal derivative terms. The authors considered 211u001eiteration methods based on the approximate factorizations of the system matrix 211u001eassociated with the application of modified Newton.
