How to create expression for time dependent heat flux on wall

  I am trying to do a multiphase simulation of hydrogen gas-liquid interaction. I am referring to a paper in which they have implemented UDF for mass and energy source terms. Also UDF for heat flux on certain wall sections.
  Is it possible to write a single UDF incorporating both the mass source term as well as the wall heat fluxes?
  Or a way to write time-dependent expressions of heat flux for selected walls in fluent setup?
