A special effort for 2D

& BeyondAccurate solvingAdvanced modelsPerformant numerical methods


Modelling eddy currents in 3DThe aim

To be faster and more robust

When using T‐φ formulationsdifficulties to deal with periodicities with solid conductorsthe use of symetries may lead to useless costly pre computationsthe use of symetries may lead to useless costly pre‐computationsautomatic definition of cuts is not working well : should be really fully automatic

O t tOur strategy :Rework the algorithms for T‐φ formulationsDevelop A‐v formulations

Magnetic Steady‐state AC 3D with meshed coils has already given satisfactory results in development version
