Convergence with reduced under relaxation and time scale factors
 
In a steady state simulation if a reduction of under relaxation factor (for pressure) and a reduction of time scale factor (pseudo transient algorithm) gives convergence with the monitor points then -

Is it fine to relay on such convergence (or) is it always a must in general to
run a few more iterations by revoking the default under relaxation factor
and with a time scale factor = 1 ?

It is a pressure based coupled solver in double precission with :
pressure --> standard, momentum --> second order, turbulence --> first order, Energy equation not involved
