Reply To: What is the difference between total heat transfer rate and total surface heat f

Hi, thank you for your response.

For a wall boundary condition(isothermal temperature wall condition), the surface integral of the total surface heat flux and the total heat transfer rate in the flux report yield the same value. 

However, as I mentioned, for a mass-flow-inlet(isothermal temperaure fluid condition), these two values are different. It is weird that the two values differ for the mass-flow-inlet. Could it be that only conduction heat transfer is considered in the surface integral of the total surface heat flux?
