B-H Curve Table
B-H curve of material is defined in this table.
It is displayed on [Permeability] tab. See [How to Set Body Attribute/Material Property] for detailed setup.

Interpolation Method |
This method is selected if the values are between the data points within a defined range of table.
Linear Interpolation Straight line is used.
Smooth Interpolation For static analysis and harmonic analysis, 3rd-order spline curve is used. For transient analysis, Akima interpolation is used.

|
Extrapolation Method |
This method is selected if the values are out of a defined range of table.
Permeability in the Free Space Permeability in the free space (μ0=4*pi*1e-7) is used.
Gradient of the Last Two Points Gradient of the last two points defined in the table is used.
Quadratic Curve Quadratic curve is used up to the saturation magnetization. Permeability in the free space is used after the saturation magnetization. It is required to specify the saturation magnetization (M=B-μ0*H [T]) in this method.
