I would like to know how to make a thermal connection between two objects in a Patran/Nastran 2021 heat transfer analysis.

Question

I did a thermal analysis on two blocks with temperatures on the top and bottom.

There was no heat transfer between the two blocks, and the temperatures were constant for each block.

I would like to know how to thermally connect the blocks.

I am a beginner just starting out, so I would appreciate as much detail as possible.

Just for completeness here is the example of using DQNEAR and also instead of thermal contact, you can use coupled convection to create connection between the 2 parts, so that you can use SOL 153 and SOL 159 to create thermal contact as well. The coupled convection feature is supported in SOL 153,SOL 159, and SOL 400.

Here include the zip file for cases of DQNEAR and coupled convection, and powerpoint.
