Possible?: Periodic conditions with non-constant mass flow rate.
 

Dear All,

In my unsteady 2-D incompressible flow simulation,I'd like to set a periodic condition at both ends of a tube with a non-constant mass flow rate, say, a sinusoidal mass flow rate varying with time, for example,

Mass flow rate at inlet = that at outlet = m*Sin(2*pi*w*t)

Is this possible? How can I do so? Many thanks!
