Surface Integration
 

Hi friends

I am simulating a heat spreader for electronic cooling. The surface area of the spreader is 20mm x 20mm.Using heat transfer report I can determine the total power dissipated from the spreader surface. My problem is I need to choose part of the surface (ex area 1mmx1mm) and determine the power dissipated from that area. I tried derived parts and generate section but nothing comes out it is always zero.

Any body can help?
