Electrowetting / droplet motion

Hi,
I want to determine the physics of motion of droplets (transport, splitting and merging) using COMSOL. I found the paper: www.comsol.co.in/paper/download/37206/Cahill.pdf
but I can't implement the simulation.
Who might be able to help me, and send some examples or model (.mph) or information about e.g. the transport speed determination of a droplet between two electrodes?

Many thanks in advance
