Simulation of Multibody Systems with Servo Constraints through Optimal Control

[OWP-2015-18] Altmann, Robert; Heiland, Jan (Mathematisches Forschungsinstitut Oberwolfach, 2015)

We consider mechanical systems where the dynamics are partially constrained to prescribed trajectories. An example for such a system is a building crane with a load and the requirement that the load moves on a certain path. ...
Time Discretization Schemes for Hyperbolic Systems on Networks by ε-Expansion

[OWP-2019-03] Altmann, Robert; Zimmer, Christoph (Mathematisches Forschungsinstitut Oberwolfach, 2019-02-12)

We consider partial differential equations on networks with a small parameter $\epsilon$ , which are hyperbolic for $\epsilon>0$ and parabolic for $\epsilon=0$ . With a combination of an $\epsilon$ -expansion and Runge-Kutta ...
