Pressurized Cylinder, Heat Generation, Concentric Cylinder, Contact Pair, coupled physics

Hi,

I am modeling two concentric cylinders with a gap between them initially in 2D Axisymmetric.

(1) I am using "Heat Transfer in Solids" and "Solid Mechanics". I have defined a contact pair in Model1>Definitions with outer surface of inner cylinder as source and inner surface of outer cylinder as destination. Chose assembly as finalization.

(2) The ends are fixed.

(3) I applied a boundary load at innermost surface of the inner cylinder so that the inner cylinder expands and touches outer cylinder. Made a contact node in "solid Mechanics".

(4) There is heat generation in inner cylinder which i have applied with a Heat Source.

I want the inner cylinder to expand and touch the outer one so that there is heat transfer from inner to outer.

Plz tell me what else i need to add in "Solid Mechanics" or "Heat Transfer in solids" so that it works.

Do i need to make a "contact" in "Heat Transfer in Solids"??

Regards and Thanks
