electrohydrodynamic modelling

I am working on EHD (electrohydrodymanic) and i want to use Ansys Fluent VOF for tracking the liquid-gas phase and the Taylor-Melcher leaky dielectric model for the EHD but i don't know how to do this. Can someone kindly assist.

This has to be done via UDFs. Fluent has an in-built electric potential equation solver but that may or may not be compatible with VOF. Furthermore, if the electric field is constant, then, no need to solve any equation for electric field. In any case, you have to write UDFs to determine and apply forces due to the existence of electric field at the droplet interfaces.
