Convergence while using icoFoam
Title
Question

Does OpenFOAM always show in the terminal if the Solution is converged or not while using icoFoam Solver? I have tried to plot residuals and continuity, while running the iterations and I am getting the correct plots. Please enlighten me. Thank you very much. Regards, Ankur

Hi ankur, Since the icoFoam is based on PISO algorithm, it will keep on running based on the endTime specified at controlDict file. say for example, if you have a problem which becomes steady state after some iterations, the residuals will fall down say 10^-5, but still the solver continues to run. You can stop the iterations manually once it reaches the desired convergence value.
