EM analysis

Where it is

Not a setup-tree node. Embedded in the application.

Controls

ANALYSIS

Analysis type

Control: choice (ComboRow)
Options: Electrostatic, Current conduction, Magnetostatics, Eddy currents

The in-app guidance depends on the case:

Where the current goes through a conductor, and the heat it makes on the way. Wants a conductivity.
The magnetostatic case at a frequency: the currents an alternating field induces in nearby metal, and the heat they leave behind. Meshes the AIR around the part, like Magnetostatics — so this re-meshes when you switch to it.
The magnetic field a steady current makes. Meshes the AIR around the part as well, because the field does not stop at its surface — so this re-meshes when you switch to it.
The potential field in and around an insulator, and the field strength against a breakdown limit. Wants a permittivity.

Frequency

Control: value (ValueField)
Unit: Hz
Value modes: none (plain entry)
Shown when: root.eddyCurrent

Mains is 50 or 60; an induction heater is tens of kilohertz. The skin depth goes as 1/√f, and the induced loss with it — at zero there are no eddy currents at all.
