Magnetic non conducting regions
Introduction
Magnetic non conducting regions in Flux allow representing bulk magnetic cores (e.g., ferrites, sintered or pressed iron powders) without taking eddy currents into account, i.e., only the B(H) characteristic in the material definition is considered, while the J(E) law, if defined, is discarded.
When a Jiles-Atherton or a Preisach model is used as B(H) characteristic in a Transient Magnetic solution, these regions enable to account for static hysteresis only (not the dynamic phenomena) and allow getting the hysteresis losses (not the full iron losses) by à priori approach.
How to create it in a Flux project
In Flux 2D and in Flux Skew, the magnetic non conducting region is a face region, while in Flux 3D it becomes a volume region. These regions are available in all Magnetic applications: Static, Transient and Steady State AC.
This region may be created as follows:
- while creating a new region, select Magnetic Non Conducting Region in the drop-down menu Type of region;
- then, provide a material for the region.
