Industry is meeting ever more complex and challenging problems, which must be solved by using state of the art mathematical and advanced computational tools. Academic institutions often have the knowledge and expertise to be of great help in this field. Further, Computational Science is a rapidly growing field to understand and solve complex problems in Society and Industry. It takes contributions from multiple disciplines to combine software, networks and IT resources to perform computational tasks. An important feature is the momentum for setting up of collaborative teams working on multidisciplinary challenges in industry and society.

This workshop is set up as a forum where both industry and governmental institutions can co-operate to solve large scale multiphysics problems. In particular the workshop will focus on strategies to increase the interaction between industry and academia in order to help industry (in particular SME) and society with advanced grid technologies, mathematical and computational tools.

After three French/Finnish workshops in  2001 (Jyväskylä), 2003 (Sophia-Antipolis), 2005 (Helsinki) on modeling, analysis and optimization for the design of coupled industrial systems, this fourth edition is multidisciplinary, combining the power of mathematics and Computational Science in applied sciences and engineering, for modeling, simulation and optimization. It is set up by a joint effort of ECCOMAS, the MASI Tekes program and

SCOMA in Finland and INRIA.

How to visit us from abroad ?




A bus will pick the participants at the Main Bus Station (Gare Routière) in Grenoble to INRIA every morning at 9:00 am, and back at 18:00.
The Bus Station is next to the Railway Station (SNCF) in Grenoble. The Railway Station is opposite to the "Suisse et Bordeaux Hotel" in which most participants have a room booked.The bus station is 200 meters from the hotel on the right of the Railway Station.
The bus, from Lazier Tourism Company, will be parked at Stand 20, 21 or 22. It will bear a "INRIA" panel on the windscreen.





Simulation and Optimization for the design of complex artefacts requiring advanced multi physics simulation and optimisation and the deployment of collaborative platforms using grids and supercomputing technologies for high performance computing, resource sharing and parallelism. The objectives of this workshop  is to bring together researchers from public labs and from the industry to discuss the methods for solving challenging problems in Industry and society, the performance of  new methods and their associated software, concerning:


° Multi-physics modelization for aeroacoustics and electromagnetics software

° Multi-level methods and adapted structured/unstructured meshes for analysis software

° Adjoint-based gradient methods, global optimization methods, Evolutionary Algorithms, Shape optimization

° Fast solvers for Image Processing

° Robust Control for distributed systems

° Grid computing technologies

° Open source middleware

Industrial Applications

° Airplane, UVA systems and drone design: drag reduction, fluid-structure optimization, noise reduction, sonic boom reduction

° Automobile design: weight reduction, aerodynamic improvements, internal engine air flow design
