Profil

In der AG Numerische Simulation werden Veränderungsprozesse aus verschiedensten Lebensbereichen wie Mathematik, Physik, Meteorologie, Hydrologie und Medizintechnik modelliert und simuliert.

Die grundlegenden  Modelle solcher Veränderungsprozesse sind dabei stets Gewöhnliche oder Partielle Differentialgleichungen. Die Analyse des entsprechenden Mathematischen Modells (z.B. korrekte Problemstellung, Existenz von Lösungen), das Finden von geeigneten Approximationen  der Lösungen durch numerische Diskretisierungsmethoden und die Stabilität dieser Approximationsverfahren sind dabei zentrale Punkte.
