Please help us to organise this event and register below!



The Munich Centre of Advanced Computing (MAC) is a research consortium which has been established at TUM to bundle research activities related to computational science and engineering (CSE) as well as high-performance computing (HPC) - across disciplines, across departments, and across institutions. After two successful workshops in 2009 and 2010, we are happy to announce our next half-day MAC Summer Workshop 2011 on July 13, 2011, where we hope to meet all our members, our friends, and people interested in our work.

Prior to the summer workshop, we are happy to host two additional meetings: The Munich Multiphysics Meeting and the Peano User Meeting that will take part in the morning of July 13. They are open to all workshop participants. For the main afternoon workshop, we are proud to have several renowned speakers as our guests. We invite our members and friends, but we'd also like to ask you to bring along your friends and students. The exact agenda can be found on our webpages ( Please register for the event before July 1, 2011, to enable us to organise everything.

With best wishes,

Hans-Joachim Bungartz, Miriam Mehl, and Tobias Weinzierl

Munich Multiphysics Meeting

The numerical simulation of multiphysics scenarios has become an essential prerequisite for many science an engineering applications. On the one hand, the high accuracy required to support further improvements of technical processes or to deepen the understanding in various scientific areas demands the inclusion of more than only one relevant physical effect. For example, the aerodynamic properties of an aircraft can hardly be further optimized without taking into account the interaction between the air flow and the structural dynamics of the wings, the simulation of chemical processes leads to a coupling between chemical reactions, thermodynamics, and (often turbulent) fluid flow. Todays high performance computing facilities offer sufficient computing power to tackle the resulting large simulations. However, questions already arising in singlephyics simulations concerning the modularity, convergence, numerical stability, and hardware efficiency become even more involved for multiphysics applications, which makes the multiphysics topic a field of vivid research accross various scientific disciplines. This meeting brings together invited experts from the different areas involved in the development of efficient simualtion approaches for multiphysics scenarios: engineering, mathematics, computer science, and scientific computing. The session is open to everybody.

Peano User Meeting

Peano is an open source software framework for grid construction, grid management, and parallel grid traversal as it occurs for the solution of partial differential equations, e.g. The pure C++ code is based upon a combination of spacetrees - an extension of the classical quadtree idea, space-filling curves, and stacks, and it comes along with a very low memory footprint.

Peano today is the basis of several applications realised as plugins of the framework. The Peano User Meeting shall bring together the community of Peano users and provide a platform to

  • present achievements and scientific outcomes due to Peano,
  • present best-practices,
  • exchange experiences,
  • announce future improvements of the framework, and
  • elaborate the requirements of future Peano versions.

The session is open to everybody. The list of invited talks comprises a selection of outstanding Peano projects with different background.

The Institute for Advanced Study of Technische Universität München is the centerpiece of TUM’s institutional strategy to promote top-level research in the so-called Excellence Initiative by the German federal and state governments. Its building is at the campus Garching if you exit the underground at the north exit. Here is also a more elaborate description how to get there from different places.
