<p>The considered model is a heat sink for an LED light.</p>
<p>The initial model is subjected to a temperature in the red highlighted area (see image below). The boundary of the model acts as the temperature sink.
   The internal heat flux constraint is used such that conduction to the right-most boudnary is prefered (orage line).
