rebuild a single turn coil feature (mf)

I try to understand how the ODE of the single turn coil feature in 2d-axy work with a coil group activated (windings are in serie configuration) with mf physic.
I think that I need to use an external current density feature and constraint the intensity with a weak contribution on the 2 windings. I have create integral operators intop1 and intop2 windings.
To impose I1=I2=I0 I write under the weak constraint node (with auxiliary dependent variable Iwinding1 added under the node with right click)
For winding 1: (intop1(mf.Jphi-I0)*test(Ispire1)
For winding 2: (intop2(mf.Jphi-I0)*test(Ispire2)
I apply Ispire1 and 2 in external density domains.
It doesn't work.
With global equations added it works better but currents are not exactly the same in winding 1 and 2.
The single turn coil feature is far more complex, the ODE is (intop1(mf.Jphi-I0)*test(Vcoil)
I don't know how to add the ODE for the potential
Someone have any experience with this?
Best regards
