Steady State Thermal – Result temperature higher than boundary condition

  Hello,
  I think I am having a problem with a project I'm working on. I am trying to do a steady state thermal simulation of some bodies. The inner one has a temperature of 1000 degrees, and it's radiating heat to other bodies.
  The problem is that when I run the simulation in the results I get that the highest temperature of the compund is around 1003 degrees.... Which should not be possible since the higher one I have is 1000 degrees, being the environment at 22 degrees. I tried with a smaller mesh but still I get a maximum temperature higher than 1000 degrees. Could there be an easy reason for this?
  Thank you,
