Hi everyone,

Can anyone help me with a few questions about SU2 and CFD?
[LIST=1]
I want to introduce a pitching moment constraint of Mz => -0.087, how I introduce that in SU2? Maybe Moment_Z < 0.087?
I don't know the axis direction and moments in SU2 and this leave me crazy.
[LIST=2]
I set the RESIDUAL_REDUCTION = 6 and the RESIDUAL_MINVAL = -6. This mean the stop criterion for the residual is until the solver achieved to -6*10^-6?
[LIST=3]
My adjoint solution, after 10000 iteration achieve to -3.5 of the residual density. Again the RESIDUAL_REDUCTION = 6 and the RESIDUAL_MINVAL = -6 is set. For the adjoint solution decrease until -6 it is need a huge number of iteration. In an shape_optimization this will cost a lot. The value of -3.5 is a satisfaction value or I need to decrease more ? What impact have in decreasing this value for the adjoint solution and for the optimization?

[LIST=4]
In the optimal shape design definition I can define the upper and lower bound for each design variable. Using the value of OPT_BOUND_UPPER = 0.1
OPT_BOUND_LOWER = -0.1 means that, each design variable can move between 0.1 and -0.1 of its initial position?

Thanks for you attention,
João Lourenço

I have the same doubt about LIST=1.


Please let me know what the answer is.
