COMSOL: Periodic inlet flow rate in a pipe

  1. Feb 23, 2010 #1
    Hi all -

    I would like to add a periodic inlet flow rate (Q(t) over an entire period T) as a BC in COMSOL. Does anyone know how to do this in 2D axisymmetric Transient Navier Stokes through COMSOL? I'm aware of the periodic boundary condition option available, but really just don't know how to use it and have found no good references to it. Any ideas or input to this problem would be appreciated.

    PS: I already have the flow rate Q(t) data vector from matlab, now I want to make it a BC at the inlet!
