Hello,
Some default settings were improved in v7.0, and some finer robustnesss oriented settings are possible (such as using a different gradient reconstruction algorithm for different variables), but otherwise, robustness of v6 and v7 should be about the same.
In your case, if you use a prescribed velocity instead of a pressure difference, what pressure difference do you have at the end ? Did you try initializing a computation by prescribing velocity and restarting with a pressure difference ? No guarantee it will work, but easy to try.
Best regards,
Yvan
