I am using 2D to model periodic flow through an open boundary with zero normal stress. I have added an integral over the surface of this boundary, as well as a global probe that reads "intop1(u) *z", where z is the hypothetical depth of my (rectangular) device. What I am trying to do is find a way to integrate the results of the probe over time so as to get a net flow rate over said boundary. Is there a way of doing this, given that the results of the probe are not produced in a set time step since they depend on the solver's time steps.
