Result comparision of CFX and fluent
 
Dear all:
now i am working on fin simulation by CFX and fluent with laminar flow model undert same boundary conditions and same mesh.

Boundary conditions are listed as flollow:
Given air's inlet velocity and temperature, air outlet pressure;
Given fin's temperature.

The profile of temperature and pressure in post-process are almost same. But there are some difference between CFX and fluent to the total heat load. The heat load calculated by fluent is almost double than done by CFX.
i doubted it maybe due to different difinition of heat flux between CFX and fluent, so anyone here met such problems before? i need you help!
thank you.
