Reply To: UDF works in planar option but not axisymmetric

[SRP]

Hi,

In axisymmetric simulations, Fluent automatically accounts for the circumferential integration when calculating fluxes and forces. In an axisymmetric case, the heat flux needs to be interpreted correctly. Fluent handles the circumferential scaling internally, so your calculations need to be adjusted accordingly. Specifically, the heat flux should be divided by 2*pi*r.

Thank you.
