Hi,

is there any possibility to get the exact radiative and convective heat flux in CFD-Post? I mean the values given in the solver output file under section "H-Energy" and "I-Radiation".

In my case there are big differences (300 W vs. 960W) between "wall heat flux" and "heat flux" in CFD-Post. From the manual xmod.pdf at page 63/64 I know the difference between these two values. "Heat flux" is the value written by the solver, "wall heat flux" is calculated in CFD-Post. The "wall radiative heat flux" ist about 230 W and the "wall convective heat flux" is 70 W but as the manual states these values are affected by edge values of adjacent adiabatic walls.

In the output file are "correct" values of 230 W (radiative) and 730 W (convective) which sums nicely to 960 W. Is it possible to follow this balance in CFD-Post? Maybe there ist some expert parameter to export the radiative and convective heat fluxes directly to the results file?
