A 5D concept for space-time optimal control problems with application to simplified Carreau flow
S. Beuchler, B. Endtmayer, U. Langer +2
This work presents a 5D concept to optimizing non-Newtonian fluid flows through a simplified Carreau flow model. We solve the optimization problem by approximating the solution of…

Efficient evaluation of forward and inverse energy-based magnetic hysteresis operators
Herbert Egger, Felix Engertsberger, Andreas Schafelner
The energy-based vector hysteresis model of Francois-Lavet et al. establishes an implicit relation between magnetic fields and fluxes via internal magnetic polarizations which are…

A parallel-in-time solver for nonlinear degenerate time-periodic parabolic problems
Herbert Egger, Andreas Schafelner
A class of abstract nonlinear time-periodic evolution problems is considered which arise in electrical engineering and other scientific disciplines. An efficient solver is proposed…
