Discrete numerical solution of strongly coupled mixed diffusion problems
This paper is concerned with the discrete numerical solution of coupled partial differential mixed problems with non-Dirichlet coupled boundary value conditions. By using a discrete separation of variables method, the proposed numerical solution of the problems is the exact solution of certain coupled partial difference system, appearing from the discretization of the continuous partial differential systems. Existence, stability, and examples are considered. (C) 2000 Elsevier Science Ltd. All rights reserved.
