Hi,

I've been reading practical tutorials and seen that a reasonable target value for RMS residual for steady state simulations is 0.0001.

However, I'm not quite sure for transient problems what is an appropriatte target value. I understand transient simulations are solved by computing a steady state solution for many discrete points in time. Each steady state solution is iterated through a number of inner loops called “coefficient loops”. What is a reasonable RMS target for each time step? I've read that 3-5 loops should allow you to reach convergence.

I've noticed CFX by default monitors the RMS for each timestep. If the RMS value for that timestep is above the target, does that mean the solution is not converged? Should I wait until all monitored RMS quantities are below the target for all time steps from there on to be confident about my solution?

What other quantities are good practice to monitor in order to trust the obtained solution?

Thanks!
