Hello Foamers,
I am trying to implement the Generalized Navier Boundary Condition beta*U_slip + mu*dU/dn + gamma*(cos(theta_d) - cos(theta_e))*n_a*delta with beta: friction coefficient mu: viscosity n_w: normal of the wall gamma: surface tension theta_d: dynamic contact angle theta_e: equilibrium contact angle n_a: normal of fluid interface (alpha) delta: contact line segment I thought the partialSlip BC would be a good starting point, but I cannot figure out how to add a constant (surface tension part) to that BC. Has anyone experience writing a mixed/robin BC for a velocity field? Thanks! Arnout |
