How to disable the Arrehnius kinetic?
 

Hi everyone.
I've implemented in Fluent a volumetric reaction rate compiling an udf. I've hooked the udf for the volumetric reaction rate.
The udf is good, but I don't know how to disable the Arrehnius kinetics keeping the volumetric reaction rate; setting 0 as pre-exponential factor and activation energy, the reaction doesn't start at all. Anyone knows how to disable the Arrhenius kinetics?

come on guys!

do you know how to do this?
I have the same question now?
