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

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...

Any idea on how to do that in COMSOL? I'm very new (< 1 week) at using it. Thanks again

I would be willing to try a swap file due to the time I have. I'll start looking at that but are there any references on how to do this in COMSOL? Thanks!

PS: ~ 156933 elements in this domain.

I'm running out of memory on my model help! 3D not axisymmetric! Pictures of geometry and mesh attached. Any recommendations on how to make this possible? This is volumetric flow through a cylinder with a thin membrane attached that is porous and utilizes brinkman's equations.

Hi all - I have a problem that I'm probably going to model in COMSOL and would love to hear some ideas on how to get the proper BCs. Attached is the picture from Truskey. Essentially, the problem consists of removing waste (water) from the membrane tube at a rate of ~ 1 mL/min with a pressure...
