Having trouble with a heat sink in ANSYS NLT

[Kevin Halagan]

Hello,
I can't seem to get the great data when I am running my heat sink model through ANSYS NLT. I feel like I am overlooking something. Is anyone experienced and has some guidance. It is a simple convection problem with a certain amount of watts running through a cooper pipe into a copper heat sink.

Can you be more specific about why you don't like the data you're getting?
