Unsteady Parabolic Field Function
Hi there,

I'm using STAR CCM+ version 7 and I'm currently trying to write a field function to define the inlet velocity of a vessel.

Currently my inlet velocity is 0.00591m/s in a vessel of radius 0.00005m.
I have defined the following field function to implement a parabolic flow profile at the inlet using this information:


I wish to apply an unsteady parabolic flow profile at the inlet to the same vessel with a velocity of +/- 0.0019 m/s

Does anyone know how I would define the unsteady velocity in this field function or be able to point me in the right direction??
