Hi,

While performing a heat transfer analysis simulation (2D, transient, coupled heat transfer model), I recorded the heat transfer across boundaries by setting up:
Solution->Report Definitions->Flux Reports-> Total Heat Transfer Rate -> Per zone flux (selecting all the walls). See the attached image - A.

At the end of the simulations I calculated the fluxes independently by:
Results->Reports->Fluxes->Total Heat Transfer Rate (selecting all wall boundaries). See attached image B.
However, the heat transfer rates I obtained were different from the above method.

Why is this? Which is the correct method?

Thanks,
