Analysis of a fume extraction duct carrying fume at 400 deg C for thermal stresses

      I have to analyse the fume extraction duct in which fumes at 400 degC is flowing. I am analyzing this in static structural. The duct is supported on guide supports which allow movement in axial direction.

      What if you specify a displacement of 5mm beforehand?

      Actually I am checking the behavior, the maximum 5 mm is allowed , I don't know whether it will be 5 or not.
      And I was able to constraint the motion by applying stopper and giving the frictional contact.

      I have one question regarding this,
      If I model the above duct as shell element, how to give different convective boundary condition on top and bottom surface?
