Seminar “Reduced Basis Methods”
- Choice of topic via email! Please find below the topics available for this seminar under “General Information -> Topics”. Please indicate 3 topic you are interested in via email to Silke Glas until February 10. The final choice will be communicated via email.
Numerical simulation has found broad application in many different fields and has become an integral part of modern day science and technology. As the models used for simulation get more accurate and complex, the required computational power grows as well. In many cases the computational, time and storage constraints imposed by the limitations of available hardware or economic considerations, do not allow for usage of accurate models. This has led to the development of Model Order Reduction (MOR) techniques that attempt to solve complex systems in real time, while controlling the resulting approximation error. Reduced Basis Methods (RBM) is a special type of MOR that has proven to be very successful in various applications. In this seminar we will brush through MOR, focusing specifically on RBM. The seminar can serve as a good preparation for a subsequent master thesis.
