Default Boundary conditions on a growing boundary

Hi all,

I am trying to simulate the case of fluid flow over a growing boundary. The fluid carries tracer particles which do not affect the flow field. These tracer particles get deposited near the walls of my domain and give rise to a growing boundary. I intend to study how the flow field gets affected by this deposition. The deposited mass can be thought of as a set of rigid spheres. So basically I need to implement no-slip conditions at this growing boundary.

Please give your suggestions on how to implement this in OpenFOAM. Thanks in advance.
