Workshop on Model Reduction Methods and Optimization (Opatija, Croatia)

The goal of this workshop is to provide a coherent set of lectures that will adequately clarify the mathematical aspects of the (optimal) control of dynamical systems, with special emphasis on optimization and model reduction methods for large-scale systems.
The Workshop is supported by European Model Reduction Network (EU-MORNET).

Invited Lecturers
Zlatko Drmač, Department of Mathematics, University of Zagreb, Croatia
Serkan Gugercin, Department of Mathematics, Virginia Polytechnic Institute and State University, Blacksburg, USA
Karl Meerbergen, KU Leuven Department of Computer Science, Leuven, Belgium
Volker Mehrmann, Technische Universität Berlin, Berlin, Germany
Tim Mitchell, Max Planck Institute for Dynamics of Complex Technical Systems, Magdeburg, Germany

Abstract
We discuss the optimal control of reactive flows arising e.g. in the construction of modern pulse detonation engines. Several major challenges have to be dealt with. Due to the nonlinear transport phenomenon and the occurence of fast moving shocks, classical model reduction techniques typically do not lead to a sufficient reduction of the model. Furthermore, typically the shock front is not resolved anymore in the reduced model. We discuss two new approaches, the new shifted POD technique and the use of innovative interpolation techniques for the treatment of fast moving sharp fronts in reactive flows.
Many challenges remain and we will discuss several open problems that arise in this context.
Joint work with Julius Reiss, Philipp Schulze, and Jörn Sesterhenn.

Venue
Workshop will take place at The Grand Hotel 4 Opatijska Cvijeta in Opatija where the lectures and accommodation is organized.
Opatija is located 90 km from Trieste by rail and 82 km from Pula by road. The city is geographically on the Istrian peninsula, though it is not in Istria County, but Primorje-Gorski Kotar County.
It is a popular summer and winter resort, with average temperatures of 10 °C in winter, and 25 °C in summer. Opatija is surrounded by beautiful woods of bay laurel. The whole sea-coast to the north and south of Opatija is rocky and picturesque, and contains several smaller winter resorts.

Mini-Workshop on Reduced Order Methods in Computational Fluid Dynamics: state of the art and perspectives

This mini-workshop is organized in the framework of COST, European Union Cooperation in Science and Technology, action TD 1307, EU-MORNET, European Union Model Order Reduction Network.

The mini-workshop topics deal with reduced order methods in computational fluid-dynamics and related aspects: domain decomposition, coupled physics (elasticity and porous media), interfaces, optimization, control, inverse problems, industrial applications, benchmarks test cases, parametrizations, sensitivity analysis, etc.

The miniworkshop is organized with the aim of creating an informal atmosphere open to discussions and exchange of ideas, visions and experiences.

This event is the first EU-MORNET miniworkshop and it is within WorkGroup 1 of COST EU-MORNET activities: methodological developments of model reduction, but we aim also to create bridges between WG2 and WG3, more related with applications and benchmarks.

Confirmed contributed talks by Francesco Ballarin (SISSA), Valentina Dolci (Politecnico di Torino), Silke Glas (University of Ulm), Stefano Lorenzi (Politecnico di Milano), Eleonora Musharbash (EPFL Lausanne), Federico Negri (EPFL Lausanne), Matteo Ripepi (DLR, Germany). Round table and discussion sessions on software developments and perspective on reduced order methods for industrial and scientific applications will follow, coordinated by Gianluigi Rozza and SISSA mathLab researchers.

Opening introduction will be given by Prof. Wil Schilders (TU Eindhoven), COST EU-MORNET chairman.

Please confirm your participation sending an email to morepas2015@sissa.it. No fees.

Annual EMI Symposium 2015

Dear EU-MORNET colleagues,

You are herewith invited to the annual EMI Symposium 2015, which will also discuss issues in the area of Model Order Reduction:

“Multiscale Dynamics and High Performance Computing”

When: Friday 4 December 2015
Where: Room 0.31, Ceres Building, TU/e campus

ABSTRACT
The ever increasing complexity of technological systems in science and engineering implies a persistent need for accurate and aggregated models that are able to predict, monitor and represent the dynamic behavior and features of physical phenomena. Typical demands on these models vary from specifications on reliability, computability, efficiency, complexity, accuracy, scalability, convergence and processing power. Despite the unprecedented advancements in high performance computing, the multiscale dynamical nature of systems causes these demands to be largely conflicting. The field of scientific computing therefore faces serious challenges in improving the precision and accuracy of modeling and simulation tools, in managing the complexity of models, and in improving the computational efficiency of large-scale models. This symposium aims to address these challenges by presenting a number of novel developments in the field of multiscale dynamical models, in model approximation and in h
igh performance computing.

Invited speakers:
Marcus Müller, Institut für Theoretische Physik, Georg-August-Universität, Göttingen, Germany
George Karniadakis, Charles Pitts Robinson and John Palmer Barstow Professor of Applied Mathematics, Brown University, Providence, Rhode Island (USA); also at MIT
Mike Cates, Department of Applied Mathematics and Theoretical Physics, Cambridge University, UK
Jan Dirk Jansen, Department of Geoscience & Engineering, Faculty of Civil Engineering and Geosciences, TU Delft
