Moving Porous Layer

I am modeling roughness in a microchannel by using a porous layer at the wall. I have set up a UDF that defines this layer and it works fine. I would now like to create a model that implements roughness and slip boundary by having just the porous layer move based on the following,


which is of the form: Kn*H*du/dy

Is there a way to do this?
