Hi everyone,
i`m trying to simulate on fluent the behavior of a partially filled vessel engulfed by fire. The problem is that in the vapor phase, i want to define a heat transfer coefficient for both radiation and convection. It`s possible to define with an UDF a heat transfer coefficient and what is the macro?

Thanks a lot
David
