Hi Santiago,
I understand you'd like to model a coil of FIVE turns carrying a current of 10,000Amps. I take it that the coil has two thick strands since you are also specific about 5000Amps per turn.

If what I've understood is right this is the way to go about :

1. Represent the coil overall physical cross-sectional area in your model without bothering about the interturn space.
2. If the model is Axisymmetric assign the current value "5000*5*2" that is 50,000+ j0 as Total Current via the Circuit Properties. Do not forget to assign it a name.
3. If the model is 2D, you will have the coil represented as two sections. Via Circuit Properties assign +50,000+ j0 as the Total Current on the right-hand section. Give it a name. Assign -50,000+j0 on the other section. Give it a different name.

I hope I've clarified your doubt !!

Prem Kumar, C
