Definition page

The Definition page displays the parameters and expressions of the correlated solution from which you can create design variables for the thermal correlation analysis when you select the Definition node in the main panel.


Parameters and Expressions
Type	Specifies the entity type to allow the solver to vary. Parameters—Lists boundary condition parameters that are available in the correlated solution. Expressions—Lists expressions that are available in the correlated solution.
Filter	Lets you filter the parameters and expressions displayed in the table for easier selection. For parameters, you can filter on the parameter name, source name, source type, and formula. The source is the boundary condition type. For expressions, you can filter on the expression name, units, dimensionality, and formula. The filters are case-sensitive, and support wildcards. The default wildcard of * displays all entries in the list. For example, to filter the list to display every entity with a name starting with the letter "a," enter a* as the filter string. Click Filter to display the filtered entities in the Parameters and Expressions table.
Parameters and Expressions table	Lists the parameters or expressions available in the correlated solution based on the active filters and from which you can create design variables. When Type is set to Parameters, the following columns are present: Parameter—Displays the parameter name. Units—Displays the parameter units. Source Name—Displays the name of the boundary condition in which the parameter is defined. Source Type—Displays the type of the boundary condition in which the parameter is defined. When Type is set to Expressions, the following columns are present: Expression—Displays the name of the expression. Units—Displays the expression units. Dimensionality—Displays the dimension of the expression. Source—Displays the name of the boundary condition followed by the name of the parameter in which the expression is used. You can click any column heading to sort the list in ascending or descending alphabetical order.
Design Variable Definition
Design Variable Name	Sets a unique name for the design variable. If you leave the Design Variable Name box blank, TMG Correlation assigns a default name based on the parameter or the expression you selected.
Design Variable Method	Specifies the method to define the design variable for a thermal correlation analysis. Substitution—Replaces the parameter or expression by the design variable. Multiplier—Multiplies one or more parameters or expressions by a design variable.
Original Formula	Displays the original value or formula of the selected parameters or expressions.
Preview of New Formula	Displays the design variable formula that replaces the original formula in the optimized solution during the thermal correlation analysis.
Add Design Variable	Adds the created design variable to the list of design variables for the current thermal correlation analysis.
Design Variables
Filter	Lets you filter the design variables by the Type, Name and Dimensionality. The filters are case-sensitive, and support wildcards. The default wildcard of * displays all entries in the list. For example, to filter the list to display every entity with a name starting with the letter "a," enter a* as the filter string. Click Filter to apply the filters and display the design variables in the design variables table.
Design Variables table	Lists the design variables with the following information. Name—Displays the name of the design variables. Value—Displays the value of the design variables. With the substitution method, the design variable initial value is equal to the original parameter or expression value. With the multiplier method, the design variable initial value is always 1. Units—Displays the units of the design variables. With the substitution method, the design variable units are equal to the original parameter or expression units. With the multiplier method, the design variable units are always unitless. Dimensionality—Displays the dimension of the design variables. With the substitution method, the design variable dimensions are equal to the original parameter or expression units. With the multiplier method, the design variable dimensions are always dimensionless. Source—Displays the source of the design variables. You can click any column heading to sort the list in ascending or descending alphabetical order or in ascending or descending numerical order. When you right-click one or more design variable, the following commands appear: Delete—Removes the selected design variables from the thermal correlation analysis. Information—Opens the Information window that lists general information about the design variables in a text format, which you can export to a text file if necessary.
