Face to Face Thermal Contact
A thermal analysis may be run in anticipation of a coupled structural analysis with bodies that are to be joined by a joint or other connection. Joints do not support heat transfer. This video illustrates two ways to include heat transfer between faces that are separated by a gap.
One is with thermal coupling, and the other is with contact conductance and a large pinball radius. Note that if contact conductance is used, it may be preferred to not couple thermal and structural models at the Model cell, so that connections can be defined independently.
