Hello developers,

I have yet another question regarding the heat fluxes. I've been digging through the code for a few days now, trying to figure out why the maximum heat flux that is in my surface_flow.dat is way different from the Total_MaxHeat that is exported in the history file.

There are a few differences I can find in the code. First of all, in the surface file, the routine calls Aux_Heat[iPoint] = solver[..]->GetHeatFlux(iMarker, iVertex) whereas the history file routine calls Total_MaxHeat = solver[..]->GetTotal_MaxHeatFlux();.

In solver_direct_mean.cpp the HeatFlux is computed after which the Heat_Visc += HeatFlux*Area; and MaxHeat_Visc += pow(HeatFlux, MaxNorm);, where MaxNorm is equal to 8.0. Then, the root is taken again of MaxHeat_Visc and is assigned to Total_MaxHeat.

So what is the difference between the normal HeatFlux and the Total_MaxHeat or Total_Heat? The latter are probably both integrated? Is there any way to get the correct maximum HeatFlux in the history file?

Thanks for your reply,

Jeffrey
