You can model a temperature change in a part, or a temperature difference between two part surfaces, or a strain.

1. On the Analysis & design tab, click Load properties > Temperature load.
2. In the Temperature Load Properties dialog box:
   1. Enter or modify the load properties.
   2. On the Magnitude tab, do one of the following:

      • Use the Temperature difference section to define a temperature load.

        If you want to apply a temperature load to an entire structure, enter the load in the Temperature change for axial elongation box.

      • Use the Strain section to define a strain.

   3. On the Distribution tab, select whether you want to attach the load to a part.

      If you want to apply a temperature load to an entire structure, adjust the bounding box to surround all the beams and columns in the structure.

   4. Click OK to save the changes.
3. On the Analysis & design tab, click Load > Temperature load.
4. If you selected to attach the load to a part, select the part.
5. Pick the start point of the load.
6. Pick the end point of the load.
