Energy vs Circuit Inductance issue

Inductance calculation

Energy

The calculation is done in ParaView

W = B*H/2 = mu*B^2/2

We integrate that over the entire domain, then

L = 2W/I^2

Circuits

L = XL/(2 pi f) = Im[U/I]/(2 pi f)

ElmerFEM

We can get magnetic field energy from Elmer

Reason

Have to set relaxation factor!

The problem is that B and H fields look ok. The problem is that H field is too large than it should be.
