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…
A reduced scalar potential approach for magnetostatics avoiding the coenergy
Herbert Egger, Felix Engertsberger, Bogdan Radu
The numerical solution of problems in nonlinear magnetostatics is typically based on a variational formulation in terms of magnetic potentials, the discretization by finite element…
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…
An efficient mixed finite element method for nonlinear magnetostatics and quasistatics
Herbert Egger, Felix Engertsberger, Bogdan Radu
We consider systems of nonlinear magnetostatics and quasistatics that typically arise in the modeling and simulation of electric machines. The nonlinear problems, eventually obtain…
