Easy question
 
Hi everybody,
i'm simulating a certain system containg a centrifugal fun.
In "solver manager" of CFX I'm monitoring the flow rate.
After 1000 iteration it oscillates beetween 60 and 80 m^3/h.
What does it mean? Which things can bring to this kynd of problem?
I've seen the streamlines and everything seems coherent.
Thanks in advance.
