Abstract:
The object of this paper is non-conforming finite elements and non-conforming finite element schemes for solving the diffusion-advection equation. This investigation is aimed at finding new schemes for solving parabolic equations. The method of the study is a finite element method, variational-difference schemes, tests. Two types of schemes are examined: the one is obtained with the help of the Bubnov–Galerkin method from a poor problem definition (non-monotone scheme) and the other one is a monotone up-stream type scheme, obtained from an approximate poor problem definition with a special approximation of skew-symmetric terms.
Key words:
non-conforming finite elements, diffusion and advection equation, finite element method, Bubnov–Galerkin method, up-stream type scheme.
