This paper develops a numerical procedure to accelerate the convergence of the Favre-averaged Non-Linear Harmonic (FNLH) method. The scheme provides a unified mathematical framework for solving the sparse linear systems formed by the mean flow and th

Mesh-based numerical solvers are an important part in many design tool chains. However, accurate simulations like computational fluid dynamics are time and resource consuming which is why surrogate models are employed to speed-up the solution process

Die Dissertation beschäftigt sich mit Parameteridentifikationsproblemen, wie sie häufig in Fragestellungen der Festkörpermechanik zu finden sind. Hierbei betrachten wir die Identifikation von Materialparametern -- die typischerweise die Eigenschaf

In this paper we discuss the identification of parameter functions in material models for elastic large deformations. A model of the the forward problem is given, where the displacement of a deformed material is found as the solution of a n onlinear

In this paper we continue the considerations of [5] (CSC/09-05). A numerical study for the parameter identification problem with linear elastic material and large deformations is presented. We discuss the numerical implementation in MATLAB and illust

In this paper we discuss the inverse problem of the identification of mechanical stresses by measuring the deformation of an electric potential field in a so called differential strain gauge (D-DMS). We derive a mathematical model, where the forward

In this paper we present some numerical results concerning the identification of material parameters in linear elasticity by dealing with small deformations. On the basis of a precise example different aspects of the parameter estimation problem are

In einem Modellproblem wird die Aufgabe der gleichzeitigen Identifikation zweier unabhängiger Parameterfunktionen bei elliptischen Differentialgleichungen untersucht. Es werden Parameterfunktionen betrachtet, die stückweise konstant sind. In einer
