Use CEL
 
I would suggest to use CEL. On the CFX Pre go to Outline menu. On the bottom left hand side you should see a tab called expression. Right click on that and click on insert expression.

You can insert an expression like (BCL-E^0.2)*257 [K] where BCL = Boundary's length. Once you create that expression you can use that expression to specify a profile. When you are specifying temperature, you should see a small button right next the value box. if you will click it you should be able to select the expression you just created.

I hope this helps. If you want more details I would suggest to look in to help and search for "CEL"

Ciao
