The flux is ALL heat passing through that facet, note it should have a sign and it is possible for postive and negative numbers to exist on the same surface. Surface HTC is defined in the manual, https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v222/en/flu_ug/flu_ug_fvdefs.html  and given it's based on "q" I would expect it to contain the convective and conductive parts.
