Residuals
 

Hi all,

Please could someone advise whether these residuals attached look normal and could be described as converged ? I am running a transient simulation of a fan with adaptive time stepping. I am also plotting the mass flow through the fan as another means of judging convergence.

You have to be the judge of that. Run a convergence sensitivity check and find out for yourself (ie - run a looser convergence and a tighter convergence and see how converged you are compared to the accuracy you are looking for).
