Techniques based on the use of separated representations, are at the heart of the so-called Proper Generalized Decomposition methods. Such separated representations were employed for solving multidimensional models suffering the so-called curse of di

Optimization metaheuristics are a powerful way to deal with many electromagnetic optimization problems. Recently, the symbiotic organisms search (SOS) algorithm was proposed to solve single-objective optimization problems. SOS mimics the symbiotic re

The accurate computation of motional eddy currents is essential for the design of electromagnetic devices such as eddy-current brakes. When the conductors are uniform in the moving direction, it is convenient to formulate and solve the problem within

This paper presents a volume integral formulation to solve eddy current problems on general polyhedral meshes. The required topological preprocessing is efficiently addressed in linear worst case complexity by using the idea of lazy cohomology genera

Projection-based model-order reduction is a powerful methodology for solving parameter-dependent linear systems of equations. Adaptive multi-point methods commonly employ a greedy strategy for expansion point placement: The location where some error

This work is concerned with error control in the numerical approximation of magnetic fields. It is shown how linearization and discretization error can be balanced with respect to a desired numerical accuracy, reflecting an uncertainty in the solutio
