constraints for asymmetric cylindrical model with a fin

i am trying to analyse a heat exchanger design and i have a cylindrical model with a circular fin attached to it.

my boundary conditions are convection with bulk temperature inside and outside the cylinder and this is for temp distribution

and now i would like to find thermal stresses i.e hoop and radial stress by appling constraints for static study with two ends fixed.

can i consider only one quarter since it is a  cylinder and asymmetric and in that case what are the constraints for the model.
