Brief description
The Bavarian Graduate School of Computational Engineering is an association of the three Master programs: Computational Engineering (CE) at the University of Erlangen-Nürnberg, Computational Mechanics (COME), and Computational Science and Engineering (CSE), both at TUM. Funded by the Elitenetzwerk Bayern, the Bavarian Graduate School offers an Honours program for gifted and highly motivated students. The Honours program extends the regular Master's programs by several academic offers:
- additional courses in the area of computational engineering, in particular block courses, and summer academies.
- Courses and seminars on "soft skills" - like communication skills, management, leadership, etc.
- an additional semester project closely connected to current research
Students who master the regular program with an above-average grade, and successfully finish the Honours program, as well, earn the academic degree "Master of Science with Honours".

Brief description
Im Projekt P6 der DFG-Forschergruppe 493 soll ein streng partitionierter Ansatz zur numerischen Simulation von Fluid-Struktur-Wechselwirkungen weiterentwickelt und an prototypischen und zugleich technisch relevanten Modellkonfigurationen erprobt werden. Für die Strömungsberechnungen wird der auf kartesischen Gittern arbeitende MAC-Code Nast++, entwickelt für die Behandlung zeitabhängiger laminarer Strömungen viskoser inkompressibler Fluide in veränderlichen dreidimensionalen Geometrien, weiterentwickelt und eingesetzt. Zur Berechnung der Antwort der flexiblen Strukturen bringt das Projekt P10 (Prof. Rank, Dr.-Ing. Düster) einen Löser zur strukturdynamischen Simulation in den partitionierten Ansatz ein. Nach zunächst vorzunehmenden Verbesserungen bzw. Erweiterungen am Ströungscode soll die voll transiente (implizite) Kopplung im Sinne der partitionierten Lösung realisiert und im Hinblick auf Robustheit und Stabilität untersucht und optimiert werden. Zur Validierung soll vor allem das Prinzipexperiment FLUSTRUC-A aus Projekt P4 (Prof. Durst, Dr.-Ing. Breuer, Dipl.-Ing. Lienhart) dienen. Ein weiterer Schwerpunkt der Arbeiten liegt auf der Bereitstellung einer modularen Software-Infrastruktur, die über einheitlich definierte Schnittstellen den einfachen Austausch von Komponenten gestattet und somit in der Forschergruppe beispielsweise zum Vergleich verschiedener Strukturlöser bzw. verschiedener Fluidlöser in unterschiedlichen Szenarien genutzt werden kann. Hierbei findet eine intensive Kooperation der Teilprojekte P6, P8 und P10 statt.

Brief description
Incomplete markets require new statistical, analytical, and numerical methods, to cope with stochastic volatilities or jumps in the stochastic processes, e.g. These are investigated in a joint project of Universität Heidelberg (with focus on modelling, analysis and statistics), Universität Bonn (with focus on numerics) and SCCS (with focus on software development). The goal of our work in the project is to integrate newly developed methods - especially sparse grid techniques - into the framework of ThetaML, a system of Thetaris GmbH that allows rapid formulation and analysis of complex financial derivatives.
Development of New Methods for the Production of Highly Reactive Polyisobutenes
| Project type | IGSSE Project Team |

Brief description
Polyisobutene are used in industry in large amounts. Depending on their molecular weight, they are required for rubber production or applied as adhesives, e.g.. More than 100,000 t of highly reactive polyisobutene are produced per year. Thus, efficiency and environmental compatibility are very important tasks. However, to achieve a high qulity and good productivity, all known production methods require reaction temperatures far below 0 degree celsius and solvents such as methylenchloirde, dichlormethane, or ethene. Recently, a new type of catalysts was developed at TUM (Lst. für Anorganische Chemie), that allows the production of highly reactive polyisobutene at ambient temperature and in solvents free from chlorine. The tasks of this group are to transfer this method developed on the laboratory scale to the scale of a production reactor, the detection of the underlying chemical reaction mechanisms, and, finally, the further improvement of the method. To reach these tasks, we will exploit synergies between chemistry and informatics by combining methods of experimental chemistry (reaction mechanisms, testing of other catalysts, heterogeneous catalysis, etc.) and scientific computing (examination and optimization of the cooling of the exothermic reactions, flow and transport processes).

Brief description
The recent development of commodity as well as high-performance computers shows that computationally and data intensive tasks can only benefit from the hardware's full potential, if both processor and architecture features are taken into account - from the early algorithmic design up to the final implementation. Evident examples are the limited memory access via a hierarchy of cache memory and the increasingly hybrid and hierarchical design of high-end systems, both complicated by the ongoing trend towards multi- and manycore CPUs, accelerators and other HPSoCs (High Performance Systems on a Chip). Against this background, this proposal focuses on hardware-aware programming in the context of several applications from Science and Engineering:
- Simulation of fluid flow problems on dynamically adaptive discretisation grids using recursive structured grid generation approaches and space-filling curves for parallelisation and cache-oblivious implementation.
- Compute- and memory-intensive Boundary Element calculations of electric field and potential distributions in the context of simulation and optimisation of High Voltage Apparatus design. (Group Prof. Bode).
- Hardware-aware algorithms for image reconstruction in medical imaging. (Group Prof. Schwaiger)

Brief description
In this project, a new type of micropumps will be examined in detail. The micropump consists of a three-dimensional array of identical pores with periodically but asymmetrically varying diameter, within which a suspension with particles to be sorted is pumped to and fro. The interplay of the flow field and of stochastic thermical forces results - according to the principles of Brownian Motors - in a directed movement of the suspended particles. As the transport direction depends on the dynamically relevant details of the system, in particular for example of the particle size, this hydrodynamical micropump can be used for a continuous and parallel sorting of particles. The Brownian motion opf small particles in a time-dependent viscous flow field through a pore with varying diameter represents a challenging and complex hydrodynamical problem. As, however, an as accurate as possible understanding of the underlying physical processes is indispensable for an experimental realization of the micropump, this problem shall be exhaustively examined within this project with the help of a combination of analytical and numerical methods. Special subjects are:
- transport properties of particles in dependence on the parameters particle size, pumping amplitude and frequency, pore shape, etc.,
- Interactions between particles via their volume and hydrodynamical effects,
- efficiency of particle sorting.
