New objective function
 

Hello,

I'm currently optimizing a nozzle in order to have a uniform mach number at the outlet. So by using SURFACE_MACH objective function the uniformity is ok but I need to have a directionnal flow at the outlet (meaning that the velocity vector have to be parallel to the nozzle axis).

So I need to compute a new objective function. The first idea is to modify an existing objective function in order to get rid of output/input problems. So let's say that I want to modify the objective function named SURFACE_TOTAL_PRESSURE.

What are the lines of the code I should modify ? When I searched about it I found many places where it appears so a little help would be helpful.

Thanks,
Kevin

Hi Kevin,
It is computed in COutput::SpecialOutput_AnalyzeSurface (along with many other surface quantities).

Hi Pedro,


Thank you very much, I have found all I need.

Once I have modified the code, must I recompile it or something else of this kind ?



Thanks,
Kevin
