Hello Claire,
If you consider only radiations, you can consider that air is transparent.
You can draw a silver cylinder in 2d axy and apply surface to ambient radiation losses with an external temperature of 20K. Initial temperature of the silver 60K. Check your material properties.
Compute with a time dependent solver.
