transformer simulation ads

dear all,

I designed a transformer in Momentum, ADS. How can I find the coupling coefficient of this transformer? Should I calculate from S-parameters?
Could someone help me?

Thank you.

this is something I found on the forum posted by another member. below is the link the member specified and I found the solution:
