Hi,
I'm new to fluent UDFs. I want to define some reaction rate in the flow volume. I know that it could be defined by the species model but as I need to use a variable in reaction constant I think its necessary to define them by a UDF. I couldn't find any tutorial related to my problem on the internet. I have some questions:
1- I add all materials and chemicals in fluent. there are two types of reactions in my case. some of them have constant kinetic parameters and some other need a variable (Irradiation which should be calculate in fluent). Should I define all the reaction rates by Species model (volumetric type reactions) even if I want to add UDF?

2- I tried to add an existed UDF file in my simulation. But I saw this error. How can I solve this problem? is it related to the code? or it's just related to compiling the file?

error:
