„The Secret of Flight - Direct Fem-Simulation of Turbulent Flow“

Prof. C. Johnson, Royal Institute of Technology, Stockholm
December 4, 2013

We simulate slightly viscous turbulent low Mach number 3d bluff body flow (including streamlined bodies) by computational solution of the incompressible Navier-Stokes equations with a slip boundary condition modeling observed small skin friction, by using a residual stabilized adaptive finite element method, referred to as Direct Fem-Simulation since no turbulence model beyond automatic residual stabilization is used. We find by duality based a posteriori estimation that mean value quantities such as drag and lift are computable to accuracies comparable to experiments.

As a key example, we show that the turbulent flow around a complete airplane is computable and inspecting solutions leads to a new theory of flight essentially different from the accepted theory by Kutta-Zhukovsky-Prandtl developed 100 years ago. We find that turbulent bluff body flow in general can be described as potential flow modified by rotational slip separation as a flow which is resolvable computationally using millions of mesh points, except in a far-field wake of little influence on lift and drag, and also is understandable through a mathematical stability analysis.

SCCH 2013: Scientific Computing and Cultural Heritage

November 18-20, 2013

SCCH 2013 is the fourth conference on scientific computing and cultural heritage to be held at Heidelberg. The conference brings together scientists from applied mathematics and computer science on the one hand and researchers in cultural heritage projects on the other hand. The main topic is the application of scientific computing techniques to improve research work in areas such as art history, archaeology, transcultural studies and similar topics.

2nd SIAM Germany Symposium

„Numerical Methods for Simulation & Optimization“

August 15-16, 2013

This two-day workshop with speakers from all existing German SIAM Student Chapters will cover a wide variety of topics including nonlinear programming, parameter estimation in ordinary and stochastic differential equation models, optimal control, design of optimal experiments, and application examples at an introductory level.

„The fundamental need of interactions between theory, experiment and simulations – A Case Study from Iterative Learning Control“

Prof. R. Longman, Columbia University, USA
July 23, 2013

Viewing the relatively new field of Iterative Learning Control (ILC) from a mathematical perspective can easily guide one to work on what appear to be the most relevant research problems, but they are in fact useless. One expects simulations to assist in focusing the research directions, but cases are shown where they easily lead one to wrong conclusions. Then the experimentalist might take over to make things work in hardware, but again he can be guided to wrong conclusions.

This case study shows that the interplay between theory, simulations, and experiments has been fundamental to the development of the ILC field, each approach helping the others to focus on the real issues and not make wrong conclusions. We note that one of the strengths of IWR is its ability to approach problems from all three directions.

HGS MathComp Fireside Chat

„Research for the King“

June 27, 2013

A mere 120 kilometers separate Mekka and King Abdullah University of Science and Technology (KAUST). The university was founded in 2009 in Thuwal, Saudi Arabia, near the Red Sea by King Abdullah.

Prof. H. Pottmann, a distinguished geometer at the University of Vienna, was recently appointed as the director of the Geometric Modeling and Scientific Visualization Research Center of KAUST. He is one of the foremost experts in the fields of Architectural Geometry and Applied Geometry, having authored several standard text books and numerous peer-reviewed journal publications. Prof. Pottmann will share his experiences regarding working at KAUST and will provide insights into his current research on Architectural Geometry and Applied Geometry.

MuS-TDD 2013 - Multiple Shooting and Time Domain Decomposition Methods Workshop

May 6-8, 2013

The workshop treats recent trends in multiple shooting for the solution of boundary value and optimization problems for differential equations, in particular optimal control. Especially for PDE, multiple shooting is discussed in the wider framework of various time domain decomposition methods. Altogether, the range from numerical analysis and algorithmic aspects to challenging applications is covered.

6th Workshop on Monte-Carlo-Methods

April 12-13, 2013

Monte Carlo methods play a significant role in today's science as well as in engineering. The workshop is dedicated to the exchange of ideas on methods as well as on the application of Monte Carlo methods.

As has been the tradition, the workshop features invited as well as contributed talks. Time and space is also available for poster contributions. Student contributions are welcome!
