Thermal Constraints dialog box

Type
Type	Fixed Temperature Fixed Temperature – SpatialApplies a fixed temperature value to the selected geometry or FE entities.The spatial type lets you map the field directly to a global or local coordinate system. Node ID TableDefines a thermal constraint with a node ID table, which contains a list of node IDs and corresponding scale factors. For each node in the node ID table, the temperature magnitude is multiplied by the scale factor.
Destination Folder
Constraint Container	Specifies the folder in the Simulation Navigator in which the boundary condition will be stored. The list includes the root container and existing folders that you created using the New Folder command. Examples of a root container include Load Container, Constraint Container, and Simulation Object Container.
Folder Manager	Displays a hierarchical listing of existing folders. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Model Objects
Applies only to the Fixed Temperature and Fixed Temperature – spatial types of thermal constraints.
Group Reference	Lets you apply the constraint to a group.For more information, see Group Reference options.
Select Object	Lets you select the geometry or FE entities on which the constraint will be applied. ExcludedLets you remove individual entities from within your selected object.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Magnitude
Temperature	Specifies the magnitude of the temperature constraint.
Specify Field	Lets you select or create a field.
Scale Factor	Defines a scale factor for the temperature magnitude.
Distribution
Appears when Type is set to Fixed Temperature.
Method	Defines how the temperature constraint is distributed over the selected objects.ConstantApplies the magnitude to the object as a constant value. SpatialUses a unitless field to map the temperature constraint to the nodes. A field is always mapped to global or Cartesian coordinates, even if it was defined in cylindrical, or spherical coordinates.
Distribution Field
Appears when Method is set to Spatial.
Specify Field	Defines how the temperature constraint is distributed over the nodes in the selected area.
Scaling ID Table
Appears when Type is set to Node ID Table.
Specify Field	Lets you define a thermal constraint magnitude on specific nodes as specified in a node ID table.
Card Name	Displays the name of the solver card for the constraint.

Additional magnitude options for boundary conditions
You can define the magnitude with a constant value, expression, or field. You can:Type a constant value directly in the box.Type an expression directly in the box. As you begin to type the expression, tooltips provide hints about valid parameter names. If you type an invalid or incomplete expression, the warning icon appears next to the box.Click and select:
Expression	Opens the Expressions dialog box, where you can select an existing expression or create a new one.For more information about expressions, see Expressions.
For more information about other options in the list, see Additional magnitude options.

These options are available when the magnitude is defined as Field.
Select Existing Field from List	Lets you select an existing field.
Formula Constructor	Lets you use a formula to construct a field. For more information, see Define a boundary condition using a formula field.
Table Constructor	Lets you use a table to construct a field.For more information, see Define a boundary condition using a table field and Define a material property using a table field.
Link Constructor	Lets you reference an existing field. You can override the field's spatial map to use the field in another location.For more information, see Linked Field dialog box.
Plot(XY)	Plots the field as an XY graph.For more information, see: Plot functions, Graph overview, and Edit display properties of graph objects.
Overlay(XY)	Available when a plot is already displayed. Overlays a plot on an existing plot. You can overlay up to 50 plots. For more information, see Overlay plots.
