Prescribed Temperature Boundary Condition—Creo Ansys Simulation
A prescribed temperature is a thermal boundary condition that fixes the temperature of certain geometry of your model. Use this boundary condition to set the temperature of selected references. The temperature is applied uniformly to the references. If you apply multiple prescribed temperature constraints to the same references, the solver uses the last one applied.
To Define a Prescribed Temperature Boundary Condition
1. After you create a new thermal simulation study, click > 
Temperature. The Prescribed Temperature dialog box opens.
Temperature. The Prescribed Temperature dialog box opens.2. Specify a Name for the boundary condition or accept the default name. Optionally click the color swatch adjacent to the Name box to change the color of the icon, the distribution, and the text displayed for the boundary condition.
3. Select surfaces, edges or vertices to which you want to apply this boundary condition. Your selections appear in the reference collector.
4. In the Temperature box, specify a real number, arithmetic expression or parameter name that evaluates to a real number, for the temperature at the referenced region. The default value is 20 C.
5. Select the units of temperature from the list.
