Claus Führer on Differential-Algebraic Equations in Multibody Dynamics

The event happens on a Friday.  A previous announcement had the wrong day.  Apologies for any confusion this may have caused.

Friday November 23, 13:15 (1:15pm), Wigforssalen, Halmstad University

Equations of motion of constrained multibody systems are differential-algebraic equations of index 3. In this talk an introduction to this class of ordinary differential equations is given and the concept of index and index reduction is introduced. Special focus will be put on the numerical treatment of these equations by multistep methods. Equations of motion can also be transformed to state space form (minimal coordinate formulation), there is a formulation based on coordinate partitioning and they occur as overdetermined differential algebraic systems. These variants have an direct impact on the numerical solution process and its quality. This will be the topic of the last part of the talk.
