Static study results problems

Hi!

Here I am with another problem from the same bag. I am trying to find out how circumference of an aluminum measuring wheel changes when temperature changes. I am using Static Study, with inertial relief and zero strain reference temperature +20° C in Flow/Thermal effects tab. Then I added External load -- Temperature(I tried both - above and below +20°C). The problem is: when I look at the deformed result - it is OK - the deformed part shrinks when temperature is below +20°C and expands when it is higher as you can see:

But when I make body from deformed shape, it is always the same when i open it in SW and chosing not to recognozie features. The circumference and other sizes stay the same. So I can't see the change in size. Any ideas? Model attached. Thanks in advance.
