About the Equilibrium Property Model
Equilibrium is a Property Model available when using the Property Model Calculator in Thermo‑Calc and it calculates the equilibrium for the given conditions.
When you use this Model with the Property Model Calculator, it is the same calculation result as when you are using an Equilibrium Calculator with the Single equilibrium calculation type.

The settings are entered on the Configuration window for the Property Model Calculator and described in Equilibrium Property Model Settings.
