General
Inductance of a nonlinear material (permeability is defined with B-H curve) is solved.
The vectors of the magnetic field and the magnetic flux density are solved.
Unless specified in the list below, the default conditions will be applied.

N/A |
A loop coil (coil) and a magnetic core (core) with gap are placed.
As the magnetic field concentrates in the gap of the magnetic core, small mesh size is applied (0.2mm).

Material property of the core is defined with B-H curve table.
If the magnetization characteristic is defined by B-H curve or M-H curve, calculation is nonlinear. Nonlinear calculation may not converge.
In such case, refer to “If the Nonlinear Calculation (B-H Curve) Does Not Converge “
