Heat thermal analysis

how to create a thermal simulation of heat transfer between 2 components that are in contact

Do you mean how to connect them so that heat can flow between them ? You can use either tie constraint for perfect connection or contact with gap conductance if there’s some thermal resistance in the interface.

yes, do you have a video tutorial?

I used tie constraints in heat transfer analysis here: https://www.youtube.com/watch?v=sfY5BEHUsmk

How about a model like this, I define there is a heating chip above the heatsink

If the parts are touching, tie constraints should work. If there’s a small gap, you can change the tolerance and enable adjustment. The master surface should be the one with a coarser mesh.

where is the problem if I get a warning like this
