For a nonisothermal simulation, Ansys Polyflow automatically integrates all quantities related to energy:
Total viscous and wall friction heating in the flow domain
Total heat source
Heat flux (Fourier heat flux) when the temperature is imposed
Total Joule effect
Convected heat along a boundary
along all boundary sets, so you do not need to define postprocessor sub-tasks for them. Results are displayed as numerical values in the Ansys Polyflow listing file.
