چکیده
In this paper we analyse the discrete maximum principle (DMP) for a stationary diffusion-reaction problem solved by means of prismatic finite elements. We derive geometric conditions on the shape parameters of the prismatic partitions which guarantee validity of the DMP. The presented numerical tests show the sharpness of the obtained conditions.

Discrete maximum principle for parabolic problems solved by prismatic finite elements
In this paper we analyze the discrete maximum principle (DMP) for a nonstationary diffusion-reaction problem solved by means of prismatic finite elements and θmethod. We derive geometric conditions on the shape parameters of prismatic partitions and time-steps which guarantee validity of the DMP. The presented numerical tests illustrate the sharpness of the obtained conditions. MSC: 65M60, 65M2...
متن کاملMaximum norm error analysis of a 2d singularly perturbed semilinear reaction-diffusion problem
A semilinear reaction-diffusion equation with multiple solutions is considered in a smooth two-dimensional domain. Its diffusion parameter ε2 is arbitrarily small, which induces boundary layers. Constructing discrete suband super-solutions, we prove existence and investigate the accuracy of multiple discrete solutions on layer-adapted meshes of Bakhvalov and Shishkin types. It is shown that one...
متن کاملOn the interplay between meshing and discretization inthree-dimensional diffusion simulation
The maximum principle is the most important property of solutions to diffusion equations. Violation of the maximum principle by the applied discretization scheme is the cause for severe numerical instabilities: the emergence of negative concentrations and, in the nonlinear case, the deterioration of the convergence of the Newton iteration. We compare finite volumes (FV) and finite elements (FE)...
متن کاملThe FEM approach to the 3D electrodiffusion on 'meshes' optimized with the Metropolis algorithm
The presented article contains a 3D mesh generation routine optimized with the Metropolis algorithm. The procedure enables to produce meshes of a prescribed volume V0 of elements. The finite volume meshes are used with the Finite Element approach. The FEM analysis enables to deal with a set of coupled nonlinear differential equations that describes the electrodiffusional problem. Mesh quality a...
متن کاملNon-negative mixed finite element formulations for a tensorial diffusion equation
We consider the tensorial diffusion equation, and address the discrete maximumminimum principle of mixed finite element formulations. In particular, we address non-negative solutions (which is a special case of the maximum-minimum principle) of mixed finite element formulations. It is well-known that the classical finite element formulations (like the single-field Galerkin formulation, and Ravi...
