Not happy
Help !
It's a bit tricky.
I've made a little Femlab model showing an isotemperature plot of the Flux die.
The effect of the holes is pretty obvious. (I wonder why I didn't drill all the way through for symmetrys' sake).
Looked at like this there is no obvious problem. There is a compression of the temperature isosurfaces but they are rather flat at the height if the hole centre...

more follows...
