Is convergence criteria of 10^-3 for continuity and momentum equations of a pressure-based method TOO HIGH?

03 October 2019 0 6K Report

I believe pressure-based algorithms like SIMPLE are dimensional and I have used convergence criteria of 10^-3 for continuity and momentum equations while using 10^-6 for energy equations. How can this be justified in a better sense?
