Moment convergence issue

Rachit · January 15, 2014, 02:40

Hi,

I am running a simulation to estimate the aerodynamic characteristics of a BWB delta wing configuration aircraft. The force coefficients are being approximated nicely, but the moment coefficient values are not converging at all, some other friends of mine working on the same design are facing similar issues. It would be great if someone could help.

Hi Rachit,

Are you finding that the residuals are converging in SU2? Could you share more information or console output?

If the solver converges ~6 orders of magnitude in the density residual, for instance, I would expect that both the force and moment coefficients should be relatively well converged.

Cheers,
Tom
