surface reaction rate UDF query

AmitKunte · July 10, 2015, 03:18

hi all,
I have a propane_combustion catalysed rxn on wall surface.
I have written a UDF(macro DEFINE_SR_RATE) and have hooked it successfully in define function hooks. Does fluent 14.5 display the custom UDF name(my_rate) in reaction mechanisms dialog box. I have checked volumetric and surfae reaction boxes in species model.But when i open the reaction dialog box i see only the default surface rxn rate parameters. How can i be sure thet the solver is using my custom rate.
please help!

Regards
Amit
