Heat conduction between a solid and the surrounding air

I want to analyze the temperature distribution of a metallic rack.

On one side of the rack is a heat source. I managed to model that. My Problem is the modelling of the heat conduction to the surrounding air. As this Experiment is under 0g there is no convection (insignificantly small) but conduction.

I am not sure if there is a function for conduction such as there is one for convection or do I have to design for example a big block arround the rack and set air as the material?

Thanks for any help!

If you want the air to conduct heat to the rack, then you have to add that material between the heat source and the metal rack. ANSYS Geometry editors have a function called Enclosure to automate that geometry creation task.

Since air is not very conductive, radiation may become a significant heat transfer mechanism. You should consider adding that to your model.
