  1. Heat Transfer into the fluid domain is positive - when referring to OSI Heat Flux or ORI Heat Flux. However, heat transfer into the domain for OSI Convective Temperature Flux is negative - because of the U dot N term in the integral. (See the chart in the acuTrans section of the Programs Reference Manual.) The total heat flux across a surface is the sum of OSI Convective Temperature Flux, OSI Heat Flux, radiation surface heat flux, solar radiation surface heat flux. In order to perform an energy balance across a control volume, all of these components must be summed. It is not possible to break out conduction and convection portions of the heat flux. (Note that Convective Temperature Flux is not the convection heat transfer at the wall - in fact the Convective Temperature Flux should be nearly zero at the wall - because it is due to the flow - and there should be zero flow at the wall.) When you sum the various types of heat flux for all of the bounding surfaces, the sum should be nearly zero - depending on convergence.
