If you are not already doing so, my first thought would be to set this up in a Transient Coupled Fields analysis system. The frictional contact this system would create between a spinning rod at the material it touches as it spins should use both structural and thermal degrees of freedom (set keyopt(1)=1): and

By default, the heat created by friction should be even shared between the contact and target sides of the interface:

If you locate the Help article below, you will see that the default value for real constant FHTG = 1 (all frictional energy is converted to heat) and default value for real constant FWGT = 0.5 (the heat that is generated by friction is evenly applied to the contact and target side on the contact interface).
