Hello,

I have two questions about the solver options in Saturne.

1) For steady-state calculations, is the "steady flow" option in the "Calculation features" the only possibility, or can we set somehow the "unsteady flow" option in a way that steady results can be obtain?
2) When I choose the SIMPLE algorithm for steady flow, I cannot change the "Number of iterations" in the "Steady flow management": if I modify the default value (10), it automatically turns back to 10 (I am using v5.beta)! Is this normal?

Many thanks in advance.

Best regards,

Daniele

Hello,

1) Yes, you can use an unsteady flow and converge to a steady state. This is actually the safest option, though it can be slow.

2) Does the value turn back in the GUI or in the code ? It seems to work in the GUI on my side.

Thank you for your reply.

The value turns back in the GUI and also in the code. If a set 1000, I save and launch the solver, the solver performs 10 iterations and stops. When I go back to the "Steady flow management" I see that the value has turned back to 10.

I will try to update to v5.0.1 and see if the problem disappears.

Thank you. Best regards,
