Magnetic materials modeling

Hi,

I´m modeling an electric machine. Magnetic materials are modeled by means of their measured data, so I am using an isotropic spline to model magnetization curves. 

I only got partial data: for instance, BH curves measurements performed up to H = 3000 A/m.

How does Flux extrapolate the curve behavior for H > 3000 A/m? straight curve with the same slope?

 

Why is this message shown:

The final derivative of points defining the spline curve of material ROTOR must be equal to Mu0. The final relative permeability is equal to: 9.9859

 

Thank you.

 

Best regards
