Define a spatial thermal constraint

The spatial type of thermal constraint lets you map the field directly to a global or local coordinate system.

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

  2. In the Thermal Constraints dialog box, select Fixed Temperature – spatial 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, choose a method from the Specify Field list to apply a thermal constraint that varies spatially. You can use an existing field or create a new field. For more information, see Using fields and expressions to define boundary conditions.

  5. (Optional) Enter a Scale Factor for the field.

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