steel shrink
 

Hello
I simulate a gas that is included in a steel tube.
the temperature is low like 2 Kelvin.
does anybody knows if CFX simulated the shrinking ( so less Volume) of the metallic tube?
or i have to run a thermal analysis
thank you

CFX is not a structural code; it will not do this by default. It could be modeled in CFX if the effect of the fluid pressure on the thermal contraction is negligible and if the tube is free to contract (simply supported) in a stress free condition by using mesh deformation and CEL.
