Applications of Model Order Reduction Methods in Industrial Research and Development

As part of the activities of the COST Action EU-MORNET, the Working Group 3 (Applications) organizes the 2nd Exploratory Workshop on 10 March 2017 in Luxembourg.

EU-MORNET. The COST Action EU-MORET brings together all major groups in Europe working on a range of model reduction strategies with applications in real-time visualisation and computing. The increasing complexity of mathematical models used to predict real-world systems, such as climate or the human cardiovascular system, has led to a need for model reduction, which means developing systematic algorithms for replacing complex models with far simpler ones, that still accurately capture the most important aspects of the phenomena being modelled. The network emphasises model reduction topics in several themes: 1. design, optimisation, and control theory in real-time with applications in engineering; 2. data assimilation, geometry registration, and parameter estimation with a special attention to real-time computing in biomedical engineering and computational physics; 3. real-time visualisation of physics-based simulations in computer science; 4. the treatment of high-dimensional problems in state space, physical space, or parameter space; 5. the interactions between different model reduction and dimensionality reduction approaches; The focus of the network is methodological, however, a wide range of both academic and industrial problems of high complexity is anticipated to motivate, stimulate, and ultimately demonstrate the meaningfulness and efficiency of the proposed action.

Meeting Objectives. This 1-day workshop presents a unique opportunity to connect European academic research and industrial development in the area of Model Order Reduction. The 2nd meeting of this kind aims at discussing the current state-of-the-art from the academic and application-driven perspective, demonstrating best-practice examples from industry and software companies, identifying existing challenges in the application of MOR and its promotion in commercial simulation software, collecting benchmark problems from a variety of different challenging application domains, and fostering the continuing bi-directional exchange between industry and academia.

The workshop is organised by Andreas Zilian and Stéphane Bordas from the University of Luxembourg.

The Exploratory Workshop takes place on Friday, 10 of March 2017 at the Chambre de Commerce, 7 rue Alcide de Gasperi, L-2981 Luxembourg.

The Luxembourg Chamber of Commerce is located in the financial district at Kirchberg and close to various European institutions. Please enter the building at the shown entrance and follow the directions labelled “EU-MORNET” to the conference room.

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

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.

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.
