Efficient computation of eddy-currents for nonlinear magnetic field problems

Herbert Egger, Nepomuk Krenn, Andreas Schafelner

Estimation of eddy-current losses in conducting non-laminated components of electrical devices requires expensive three-dimensional simulations. Various approximations are therefor…

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…

Goal Oriented Adaptive Space Time Finite Element Methods Applied to Touching Domains

Bernhard Endtmayer, Andreas Schafelner

We consider goal-oriented adaptive space-time finite-element discretizations of the parabolic heat equation on completely unstructured simplicial space-time meshes. In some applica…
