surface reaction UDF
 
Hi!
I compiled UDF for surface reaction and I selected it in the User-De ned Function Hooks panel; however, I donot see any reaction rate that I compiled.
How can I use the compiled surface reaction?

Because it is surface reaction, I think I should see this reaction from the boundary condition, but I just see the reaction from the species tap. It connects the surface reaction mechanism, which is not the reaction that I compiled.

In addition, what is the NUM_SPECS?

for example, I saw it from the UDF manual

/* Species numbers. Must match order in Fluent panel */
#define HF 0
#define WF6 1
#define H2O 2
#define NUM_SPECS 3

I saw many people use this NUM_SPECS in surface reaction UDF. I can not find this material from the fluid list.

Thanks
