Guevara Guest Posts: n/a	hi! all I would like to write udf form. can anybody help me!! I want to add heat flux into the cathode. The cathode fall heat flux is expressed as Qc=5Jc(Tgas-Twall)kb/(2e) and the energy lost by the arc in the vicinity go the anode is expressde as convective, radiative, Thompson effect and condensation of electrons. I don't komw what to write udf forms and how to use udf macro.
