hey guys
i have a cubic zone with pressure boundary conditions and modeling natural convection bouyoncy driven flow. and inside that cubic zone i have another small cubic zone connected form interface boundary condition to the bigger one cubic zone.the smaller one having a wall inside itself and heat source is difined on that wall surface as W/m2.

my quistion is that for defining source terms:

>>> is it enough to define source term for energy in only smaller volume (smaller cubic zone) fluid panel to postprocess complete temperature contour....?

thank you in advance
