Equilibrium Property Model Settings
Equilibrium is a General 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.
Configuration Settings
The settings are found on the Property Model Calculator when Equilibrium is selected under General Models.
When working in the Configuration window, click the Description tab for more information about the Model.
For the details about the Condition Definitions, Calculation Type, Timeout in minutes, Parallel Calculation, and other calculation associated settings, see Property Model Calculator: Configuration Window Settings.
Equilibrium Minimization Strategy
The Minimization Strategy setting is used to ensure that the most stable minimum under the specified conditions is computed.
With either the Global test preferred or Local minimization preferred setting, the program cycles through options before it gives up:
- For Global test preferred the minimization starts with a global test and if that fails it runs full global minimization.
- For Local minimization preferred the minimization starts with a local minimization, in case of failure it tries a global test and finally a full global minimization.
If you choose Local minimization only or Global minimization only, the program just tries the one setting and gives up if it fails.
For general information about global minimization, see the topic related to the Console Mode command, GLOBAL_MINIMIZATION.
Quantity Definitions
For Quantity Definitions define Q1. Click the 
Add button to define additional items and the 
Remove button to delete items.
Then from the lists, choose the variable for each quantity to define. The quantities are called Q1, Q2, Q3 and so on.
All quantities that normally can be obtained from an equilibrium calculation can also be obtained when plotting the results.
Function Definitions
For Function Definitions, define Function 1. Click the Add button to define additional items and the Remove button to delete items. In the left field edit the default name of each function and enter the function itself in the right field after the equal sign.
To learn about using variables and functions, in Graphical Mode, see T_07: User-Defined Functions and in Console Mode, see example 44 .
You can also use Console Mode syntax when entering the function.
Plot Renderer Settings
Plot Renderer and Plot Renderer: Configuration Settings
When setting up your calculation on the Plot Renderer and/or Table Renderer, the following axis variables are available for the conditions defined on the Property Model Calculator.
All quantities that normally can be obtained from an equilibrium calculation can also be obtained when plotting the results as well as the defined functions.
