Fluid-structure interaction problems, as well as many other multi-field problems, have received much attention in recent years and their importance is still continuously growing. The main reason for this is that they are of great relevance in all fields of engineering (aerospace, bio, civil, mechanical, etc.) as well as in the applied sciences. Hence, the development and application of respective modeling and simulation approaches have gained great attention over the past decades. While modeling and simulation of most relevant problems were far out of reach still a couple of years ago, this possibility is now available or only a short distance away– thanks to advances in computational power, computational modeling approaches and methods.
In recent years research in the area of computational fluid-structure interaction has seen great progress. But most of the individual topical areas are still seeing heavy research activities. Besides more theoretical aspects and the beginning of an in-depth mathematical analysis some current endeavours in this field are: the advancement from special purpose or special problem to quite general approaches; the desire to capture very general and complex systems; and the exigent need of robust high quality approaches for complex cases, i.e. approaches that have the potential to turn over from being a challenging and fascinating research topic to a real development tool with real predictive capabilities.
One problem for people trying to do high level research in this area is the multitude of topics one has to be familiar with – from computational fluid dynamics to computational solid dynamics, from efficient solver of large scale systems to coupling schemes, etc. And for real progress and high quality research or applications it is important to have the essentials in all these fields and their respective interplay available. On the other hand there are neither good text books, nor good courses – at university level or outside – available. This is exactly the huge gap that this CISM course tries to fill.
The aim of the course is to bring together world leading experts in the area of computational fluid-structure interaction and beyond (more general multi-field and multi-material problems). The course tries to not only look at the problem from one specific point of view but from very different perspectives. These different perspectives refer to both the methods used and to the types of fields covered as well as to the types of applications. As for the fields: it will cover all different types of fluid fields – from compressible to incompressible, etc. – and also different structural fields – large deformations, thin-walled, rigid bodies, nonlinear materials, bio solids, etc. As for the methods: the course will cover very different discretization schemes – from finite elements to finite volumes to spectral/hp methods and multibody dynamics. It will also cover the different ways one can formulate such a problem, i.e. different moving grid and fixed grid / immersed boundary approaches. The most important coupled solution strategies and their range of applicability (w.r.t. fields and methods) will also be dealt with in detail: from partitioned to monolithic, from staggered to semi-implicit to strong coupling schemes. As for applications: the course will cover some of the most important application areas, from aero-(thermo-)elasticity (fixed wing and rotary wing) to aerospace, from bio-engineering to yacht engineering, from automotive engineering to wind energy, etc.
The course is addressing a rather wide audience: from doctoral students to more senior researchers (from all different engineering disciplines as well as the applied sciences); in addition it will also be interesting for people from industry including commercial software companies.
