I am having some doubts over some convergence issues. The default convergence criteria for fluent is 0.0001. So if my solution converge with the default criteria it is correct? For a change, i set a very high convergence criteria 10^-10 my residual graph keeps going down until a point where everything starts to be in a straight line(constant), Do i use that results? it seems to be a more reliable result.
Re: Convergence Criteria
when your results are converged, they stop changing.
ie. check then check again 100 iterations later, if they look the same then they are converged.
