Hi,

What do you want, more precisely, to specify as function of time? The inlet velocity?

The variable for time in CFX is [b]t[b].You main specify the inlet velocity Uin, for example, as Uin = 5 [m s^-1] + 2 [m s^-1]*sin(2*pi*t/4 [s]). 4 [s] would be the period of the sin function.

Regards,

Rui

if a pulsation function is needed, the function of "step" may be used.
