You can set the temperature for the system level temperature by selecting the top level assembly in the System Tree, and setting the Temperature on the Calculation Data tab. The temperature that you set at this level will be used for all lower level parts and assemblies unless it is overridden at a lower level.
You can apply a different temperature to any lower level assembly by selecting that assembly and applying a different temperature on the Calculation Data tab for that assembly. If the temperature on the Calculation data tab shows #.# then it is using the temperate from the next higher level.
For any component you can adjust the temperature used for the calculation by applying a Temperature Rise or a Temp Override on the Prediction Data tab for the selected part. A value entered in the Temperature Rise field will be added to the next higher assembly temperature, and a Temp Override will be used in place of the next higher assembly temperature.
