metal wall model; like shell and brick interface!

[Mafranc]

I have ansys 13.
My problem is to create a model for a metal wall heated on one side, inside which there is an insulating inside and see how it deforms.
I don't have any external constraints on the wall.
on the warm side I impose conveztion + irradiation, on the cold side only irragiamento.
the wall consists of an iron box (often steel 3mm), inside which there is the insulating (often 100mm); , wall size 4x2m.
intention of my common sense is brick for the insulating and shell for the wall, but I do not know how to interface them and if in the model I must also insert the wall thickness on the shell elements.
I imagine the questions are trivial to you, but not to me that I am new.
Thank you and good day! :

good norm would be to repenetrate before!!!

I apologize for ill-education, I am frank, graduating in mechanical engineering. little work experience, cad 3d made some course with solid works, and are a self-taught slender

francesco can rightly try as you say to shape the insulating as brick, steel walls as shell and then impose beyond the boundary conditions that you also say a contact between insulating and walls.
the analysis will be split into two parts: a first only thermal part that will find the distribution of temperatures (here you can model the resistance of heat contact) and a second part that, starting from the calculated temperature field will go to find stress.
do you think you use ansys workbech or the classic?

I apologize for the ritado, but it was due to a necessary time to take a little hand. I use the classic. I created the "box", I can mesharlo in brick, but not in shell. brick to 8 knots, shell to 4 should be compatible.
I made a block, brick meshato and then remeshato the shell areas.... Could it be because of this wrong procedure the failure of the result?
