the expansion will be based on the coefficient of thermal expansion for your component and the difference between the temperature you apply to the body and the zero strain temperature you apply in the property boundary conditions.
something important here, make sure you choose a body temperature. there is no thermal gradient development with the temperature boundary condition so it would be like super cooling only the face of that part. if you need a thermal gradient, you'll need to run a thermal analysis first and then import the temperature distribution.
Thank you Jared. In going thru this exercise I found out also that I needed to keep the Input Temp @293 K in my case. I had changed it to Deg F, which was throwing my numbers off based on some hand calcs I was doing. Apparently it is a bug of somekind that SolidWorks is working on.
