I want to model thermal contact resistance between 2 coincident surfaces in Ansys AEDT 2024 (Shown attached)

I figured this would be as easy as ctrl+selecting both surfaces -> right click -> Assign Thermal -> some option about contact resistance but apparently this isnt the case.

I also saw the option for conducting plate where I could specify the thermal resistance. If I can use that option, which of the 2 surface do I turn into a conducting plate? Just one? Both?

Another method I am wondering is do I make a copy of one of the bodies -> extract just the face from the body (Create object from face) -> Simplify face into a sheet -> Assign thermal -> Conducting plate. If I can do this method, do I leave the other 2 bodies untouched? Then it's essentially a conducting place as a sheet sandwiched between Object A and Object B

Hi, 

Thanks for reaching out to support. You can just select the smaller cuboid's shared face and then assign the contact resistance. Hope this helps. 

Best,

I am replying to my original post with a different instance of the same problem. I am right clicking the smaller cuboid's face and do not see an option to assign the contact resistance. I am using the Icepak module. See attached....
