Neither of the two analyses you performed captures the physics of the heat production mechanism. I don't know what it is myself. It could be friction in some cases or possibly internal damping. If you wanted to based it on internal friction you could do a direct two way coupled thermal-structural (thermoelastic) analysis like Example 2.6.3 in the APDL Coupled-Field Analysis Guide.
