Define thermal constraints

1. Choose Home tab→Loads and Conditions group→Thermal Constraints .

2. In the Thermal Constraints dialog box, select Fixed Temperature from the Type list.

3. In the Model Objects group, click Select Object and select the geometry or FE entity to which the thermal constraint will be applied.

4. In the Magnitude group, define the thermal constraint in one of these ways:Select Expression to use a constant value or expression to define the magnitude. For more information, see Expressions. Select Field to define a thermal constraint magnitude that varies with time. From the Specify Field list, choose a method to create the field. For more information, see Using fields and expressions to define boundary conditions.

5. (Optional) In the Distribution group, choose the method for distributing the temperature over the geometry or FE entities:Select Constant to apply the magnitude to each selected item. Select Spatial to use a unitless field to map the temperature to the nodes.

6. Click OK.The constraint is applied to the model.
