How to model thermal insulating materials?

Ewen Rai Dec 14, 2017 11:06 AM

When I simulated a basic design of two materials with a thin sheet of thermal insulating material in between them. There was no difference in temperature if I hadn't have put the TIM in it.

Is this correctly modelling it or are there betters ways to introduce TIMs into a simulation?

I'm not sure what your setup is so its hard to say what may be going on, but make sure that you have a thickness of at least 2-3 nodes to get accurate results

Use Insert - Thermal Joint or Contact Resistance. (I think Contact Resistance is part of the electronics cooling module)
The interface will have 0 thickness but a thermal resistance will be applied.
