Solving eddy current problems formulated by using a magnetic scalar potential in the insulator requires a topological pre-processing to find the so-called first cohomology basis of the insulating region, which may be very time-consuming for challenging industrially driven problems. The physics-inspired Dłotko–Specogna (DS) algorithm was shown to be superior to alternatives in performing such a topological pre-processing. Yet, the DS algorithm is particularly fast when it produces as output not…

Cohomology in 3D Magneto-Quasistatics Modeling
Several definitions of cuts are surveyed, defined as generators of the first cohomology group over integers of a finite CW-complex, which has the virtue of providing an automatic, general and efficient algorithm for the computation of cuts.

Hodge decompositions and computational electromagnetics
The handling of topological aspects in boundary value problems of engineering electromagnetics is often considered to be an engineer's art and not a science. This thesis is an attempt to show that
On making cuts for magnetic scalar potentials in multiply connected regions
The problem of making cuts is of importance to scalar potential formulations of three‐dimensional eddy current problems. Its heuristic solution has been known for a century [J. C. Maxwell, A Treatise
An algorithm to make cuts for magnetic scalar potentials in tetrahedral meshes based on the finite element method
It is shown that a finite element discretization can make the problem reduce to that of harmonic functions subject to peculiar interelement constraints and the effective degrees of freedom in the element assembly are identified with topological constraints.
Efficient generalized source field computation for h-oriented magnetostatic formulations
The aim of this paper is to present a generalization of STT called Extended Spanning Tree Technique (ESTT), which is provably general and it retains the STT computational efficiency.
