Regarding DEFINE_VR_RATE , what happen to the Arrhenius Equation settings in reaction Panel?

      Hi, I am Ajith, Iam pretty new to the Fluent-UDF related topic. I have a query. nWhile hooking a DEFINE_VR_RATE ( user defne reaction rates) for three reactions, what values i need to provide in arrhenius equation settings in reaction panel ( pre exp factor and activation energy). As we are defining the reaction rates already in udf then why it is necessary. Why the arrehenius reaction window not disappearing? Or is it necessasy to input that values also. I cant find any lead to this from manual. May be i am not able to find. Manual mentioned to enable volumetric reaction while hooking udf.nCan anyone help in this, also the same thought process i have for define_sr_rate udf too.nn

      Provide stoichiometric coefficients. The rate is provided by the UDF. n

      Yes I have provided the stoichiometric coefficients. Even the rate described by hooking UDF , what about the arrhenius reaction rate options in the window?.
