....method to approximate the NEWTON KRYLOV SCHWARZ METHODS 3 Newton step. These methods have been used in computational fluid dynamics for some time [5, 6, 20] This paper is one of the first to apply these methods to Richards equation. Multigrid methods have also been applied to Richards equation, [10, 28, 34, 35]. In x 2 we describe the nonlinear and linear solver issues raised by Richards equation, introduce some notation from [27] for domain decomposition, and use that notation to describe our approach to Schwarz preconditioning. In x 3 we report numerical results for the solution of a finite element ....

....gives a brief description of some of the numerical methods used in the PREQS code. 4. 1 Discretization The discretiztion scheme employed is a cell centered finite difference scheme equivalent to the expanded mixed method of Arbogast, Wheeler and Yotov [1] and analyzed for Richards equation in [5]. We now describe the finite difference scheme employed in solving the system (1) 2) We consider a rectangular two or three dimensional domain, Omega Gamma with boundary Let ( denote the L 2( Omega Gamma inner product, scalar and vector. We will approximate the L 2 inner product ....
