Hello,
I have a little problem with setting the coefficients up for the wing optimization using FFD. Everything is working fine, but my adjoint solution takes way too long and converges to really small values I do not need. Can anybody tell me what parameters I need to change, so my convergence is stopped a bit earlier, Last lines of the adjoint convergence log10[Maximum residual]: -1.6298e+01. Maximum residual point 1103, located at (-1.9286e+02, 3.8571e+02, -4.5000e+02). Iter Time(s) Res[Psi_Rho] Res[Psi_E] Sens_Press Sens_AoA 2480 0.635330 -18.364197 -18.736024 -5.4461e-02 -2.4966e-03 2481 0.635222 -18.318372 -18.717016 -5.4461e-02 -2.4966e-03 2482 0.635114 -18.351926 -18.744432 -5.4461e-02 -2.4966e-03 2483 0.635005 -18.387036 -18.736493 -5.4461e-02 -2.4966e-03 2484 0.634907 -18.379428 -18.740495 -5.4461e-02 -2.4966e-03 2485 0.634804 -18.372618 -18.700524 -5.4461e-02 -2.4966e-03 2486 0.634697 -18.402309 -18.784623 -5.4461e-02 -2.4966e-03 2487 0.634589 -18.331247 -18.702867 -5.4461e-02 -2.4966e-03 2488 0.634481 -18.326309 -18.741878 -5.4461e-02 -2.4966e-03 2489 0.634376 -18.363654 -18.749159 -5.4461e-02 -2.4966e-03 2490 0.634268 -18.340797 -18.710770 -5.4461e-02 -2.4966e-03 2491 0.634163 -18.358591 -18.752570 -5.4461e-02 -2.4966e-03 2492 0.634058 -18.367746 -18.768742 -5.4461e-02 -2.4966e-03 2493 0.633951 -18.364933 -18.775686 -5.4461e-02 -2.4966e-03 2494 0.633843 -18.360979 -18.767785 -5.4461e-02 -2.4966e-03 2495 0.633736 -18.327877 -18.686616 -5.4461e-02 -2.4966e-03 2496 0.633629 -18.361588 -18.736146 -5.4461e-02 -2.4966e-03 2497 0.633522 -18.358536 -18.751150 -5.4461e-02 -2.4966e-03 2498 0.633415 -18.387406 -18.729346 -5.4461e-02 -2.4966e-03 2499 0.633308 -18.392014 -18.777462 -5.4461e-02 -2.4966e-03 -------------------------- File Output Summary -------------------------- Writing comma-separated values (CSV) surface files.
