first define the speces u want.define --> species.and check materials for the species in the system.then you can write a source udf...format for which is given in udf manuals.Then u can attach the source term to the species in the fluid domain.

Hello,

And what about surfacic species source? It looks like there's no way to implement a user-defined source term for surfacic species, besides the surfacic reaction rate. Is it possible? through which UDF macro?

Thanks in advance.
