Hello, everyone,

I am trying to simulate surface reaction with a micro-combustor by importing chemkin mechanisms into fluent. however, I met two problems.

First, I need to know the species ID of some particular species. Since I have both gas phase species and surface site species. I wonder what is the sequence of species in the species mixture panel, gas phase species first or site species first?

Second, I want to use UDF to define the surface reaction rate of some surface reactions. Since I have 50 surface reactions to define, I want to use a 'for' structure to loop over all the reactions I want to define according to their ID. How can I do that in ANSYS fluent?

Thanks very much!
