Talking dynamic contact angle - oil & water

Hi,

I am trying to model the movement of water droplets on a layer of oil coated on an inclined plane (so that there is a body force on oil as well as water droplets) First of all, there is no option in fluent for imposing a contact angle between two phases (oil and water) other than at wall. .

Next, I couldn't find a proper way through UDF to impose a dynamic contact angle on the water droplets moving over the oil ! Although I can impose the dynamic contact angle on water droplets moving over a wall, is it possible to apply the contact angle at the oil surface rather than at wall ?

Or is fluent capable of imposing the dynamic contact angle between oil and water by itself ? (which I highly doubt so but still I can see some convincing results after the simulations so far without a UDF!)

Any kind of help would be really appreciated, coz I am stuck here for quite a bit of time.
