I am running some simulations to get the lift and drag coefficients on an airfoil.
Now that I have been able to get a high-quality mesh, my residuals do not converge as early as they used to (around 2000 iterations previously). the convergence criteria for the residuals are the same (1e-6). although the lift and drag coefficients do not change much after about 1500 iterations with this new mesh (the first two digits after the decimal point stay the same), Is it okay if I just take the values as they are after 2500 iterations or do I need to iterate some more?
also, what number of iterations is good?
