    Description / Table of Contents: Zusammenfassung Das Ziel dieser Mitteilung ist die Verallgemeinerung der Anwendung der gruppenexpliziten Methode [1, 2] auf die numerische Lösung einer nichtlinearen parabolischen Differentialgleichung zweiter Ordnung. Die Methode wurde an der Burgerschen Gleichung für verschiedene Anfangs- und Randbedingungen getestet. Es zeigt sich, daß die Methode genau und vergleichbar mit existierenden Differenzenverfahren ist.
    Notes: Abstract The aim of this paper is to extend the application of the Group Explicit method [1, 2] to the numerical solution of a non-linear parabolic partial differential equation of second order. The method was tested out on Burger's equation for various initial and boundary conditions. It can be seen that the method is accurate and comparable to existing finite difference methods.

    Notes: In this paper, the formulation of six-point and nine-point finite element equations for the solution of the diffusion-convection equation is presented. The six-point equation requires the solution of a tridiagonal system of equations and the nine-point centred equation is treated as a solution of a boundary value problem which leads to a large linear system of equations.Some numerical experiments are presented and the comparison with existing methods is included.
