About Thermal Contact Resistance

[Anonymous]

What is the default thermal contact resistance between two aluminum plates when I don't assign any surface material between them? Does autodesk CFD regards these two plates as one big plates?

Hi @Anonymous 

By defalut there is no contact resistance between two solids in CFD.

You will have to define with a surface material.

Hope this help.

Hi Benoit,

Thanks for the answer. The "surface material" you mentioned is to assign "contact resistance" material to a surface, right? 

As below tutorial shows:
