S1m0n1 is on a distinguished road
I'm working on a project that models the flow in a 2D room. I have my convergence criteria set to 1e-6 but the residuals have been following a similar pattern no matter how many iterations I do.

Should I just try more iterations until it straightens out or can I say that my solution has converged since it follows a pattern?
