Hi,
I would like to ask you if someone has tried to investigate the dependence of the flow regime (steady or unsteady) that is found by icoFoam Solver for a given problem on the tolerance set for the linear solver ?

In fact, as I reduce the solver tolerance, I notice that the Reynolds number corresponding to the onset of unsteady flow decreases.

Can you figure out how can this affect the accuracy of the results.

Thank you,


Mehrez
