How to Model Face to Face Thermal Contact in ANSYS Workbench Mechanical
Ғылым және технология
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.

you saved my day. I had a thermo-structural problem and needed exactly this. Thanks a lot
Great explanation
thanks
why we used pinball command in this thermal analysis

The pinball gives the distance across which the surfaces will find each other to make the contact connection. If you set the pinball radius to a value smaller than the gap, the program will not consider the two surfaces in contact. The default is zero, and since the surfaces are obviously more than zero distance apart, you need to put another number in there.
