In reality all I need is an arbitrary patch where I can measure. I am relating to comsol, because this is where I have used this in the past. Does OpenFOAM have a "continuity" boundary condition? I am thinking of Comsol's definition of it, which is basically a patch that you can use to integrate scalars such as pressure, for example. This BC can also be used to increase mesh resolution through it "without" affecting the flow.
