Hi,

Relating to the Caradonna test case. Why does SU2 gives 0 trust and torque for hovering? The test case basically stops immediately after CONV_STARTITER. (convergence criteria is satisfied since all the coefficients are 0.)

And I don't understand why are the origin set to:

% Reference origin for moment computation
REF_ORIGIN_MOMENT_X = 0.25
REF_ORIGIN_MOMENT_Y = 0.00
REF_ORIGIN_MOMENT_Z = 0.00

Can someone explain these? Or there are some bugs related to rotating frames?

Kind Regards,

What version of SU2? There was a bug in moving slip walls, but it fixed in the current version (7.0.6)

I see, thanks. I used 7.0.3. With the latest code the results look better.
