i am designing a finned tube heat exhanger for thermal stress analysis(static stress) by considering a section of it( cylindrical tube with one fin) and it is a part model.i have applied boundary conditions as covective heat transfer coeff and bulk temp on both inside and outside the cylinder and  i have fixed one edge for stress analysis i.e top end.i could not figure out how to provide insulation to both ends of the cyinder.
