Hi,

Is it possible to implement a volume integration of Mach number in SU2 to evaluate convergence? I'm running a hypersonic inlet study and would like to know when the internal shockwaves have reached stable positions which isn't easy to determine just from the outputted residuals alone.

I know I could plot the solution at regular intervals to manually check but I was hoping for an automatic way of doing it, possibly by outputting it into the history file. If not currently possible is this something I could easily implement into the code myself?

Cheers.

Hi Mike,

you can do it similar to the way described here:

You can compute the Mach number at a point by using

 su2double Ma = sqrt(node[iPoint]->GetVelocity2())/node[iPoint]->GetSoundSpeed();
