It can be Courant-Fridrih-Levy number (I think that was the full name...) it is related to unsteady flows and represents the effect on the timestep... You can find more in net or users guides...

May be it is a good idea first to search in the forum.... this is an advice to all new members.... do not fill the forum with questions that were solved.
