Entwicklung eines automatischen Gitterdeformationsalgorithmus zur Strömungsberechnung um komplexe Konfigurationen auf Hexaeder-Netzen
… efficiency increase of a new algorithm for the deformation of computational grids for numerical fluid flow simulation and its application to complex configurations. At the beginning an analysis of different methods for grid deformation, that are frequently used, is done. It is shown, that their …

Evaluation of optimal control-based deformable registration model
… is to find an approximation of a reasonable deformation which transforms one image to match another based on a chosen similarity measure. A reasonable deformation can be thought of as one that is physically realizable. A number of models, guaranteeing reasonable deformations, have been …

Eine numerische Methode zur Bestimmung erweiterter flugdynamischer Derivativa durch aerostrukturdynamische Simulation
… central differencing on structured multi-block grids. Several numerical standard techniques for simulating supersonic, unsteady, turbulent flow are employed and have been partly extended in the code, e.g. unsteady inflow/outflow conditions. The quasi implicit time integration based on Jamesons …

Numerical Analysis of Flux Reconstruction
… the impact of higher dimensionality and grid deformation. It is found that both expanding and contracting grids – essential components of real-world domain decomposition – can cause dispersion overshoot in two dimensions, but that FR appears to suffer less that comparable Finite …
