Fluent Convergence Problem

nick978 · July 12, 2011, 16:27

Hello,
I have a system where I inject particles for around 15 seconds and let them settle over time. When I run the program it says that it converges after only 13 seconds even though there is still an incoming velocity as well as more particles. Does anyone know how I can fix this problem and get real answers.

Thank you,
Nick

Maybe your convergence criteria is too low. Go to the tab "Monitors" and check the option Residuals, you may want to make the convergence value lower.

Good luck!
