Hi

I have a problem with Fluent UDF for a mass source term. I'm modelling a catalytic reaction, (steam reforming) with complex reaction system. So I didn't activate the reaction and finite rate chemistry part in the fluent. Just focused on the source terms. So I defined source terms for hydrogen, methane, water,co,co2 and nitrogen. The overall mass source considered zero as we have overall balance in mass. But whenever i enable the UDF and load the library. It seems that Fluent does not consider my UDF for reaction at all. The results are the same as a stream without reaction.

Do You have any idea.

Thanks

Natan
