Setting Surface-To-Surface contact among bodies for thermal analysis

Setting Surface-To-Surface contact among bodies for thermal analysis

(OP)
Hi everybody!

I'm trying to simulate the thermal insulation of a railway vehicle. The whole assembly comprises about 400 solid bodies which are in perfect contact (touching, according to an analysis of interference among all the bodies)
In the .sim file, I want to set the boundary condition "surface-to-surface" contact among every bodies automatically, without having to establish the contact between each face pair, one by one.
I don't know which Distane Tolerance (in the Automatic Pairing Dialog Box)I should introduce.
Thanks!!

By the way, the software I'm using is Siemens NX 7.5.
