On the convergence of higher order finite element methods for nonlinear magnetostatics

Herbert Egger, Felix Engertsberger, Bogdan Radu

The modeling of electric machines and power transformers typically involves systems of nonlinear magnetostatics or -quasistatics, and their efficient and accurate simulation is req…

Error analysis for a viscoelastic phase separation model

Aaron Brunk, Herbert Egger, Oliver Habrich +1

We consider systematic numerical approximation of a viscoelastic phase separation model that describes the demixing of a polymer solvent mixture. An unconditionally stable discreti…

A magnetic oriented approach to the systematic coupling of field and circuit equations

Herbert Egger, Idoia Cortes Garcia, Vsevolod Shashkov +1

A novel strategy is proposed for the coupling of field and circuit equations when modeling power devices in the low-frequency regime. The resulting systems of differential-algebrai…

Global convergence of iterative solvers for problems of nonlinear magnetostatics

Herbert Egger, Felix Engertsberger, Bogdan Radu

We consider the convergence of iterative solvers for problems of nonlinear magnetostatics. Using the equivalence to an underlying minimization problem, we can establish global line…

Stability and convergence of the penalty formulation for nonlinear magnetostatics

Herbert Egger, Felix Engertsberger, Klaus Roppert

The magnetostatic field distribution in a nonlinear medium amounts to the unique minimizer of the magnetic coenergy over all fields that can be generated by the same current. This…
