DEFINING A SOURCE
 

Hi;

I want to define some species mass source through one of my WALL B.Cs. I know the quantity of my source for each face, but I don't know by which macro (DEFINE_?) I can do it?

I know about DEFINE_SOURCE macro but it works for all the domain.

CAN ANYONE GIVE ME SOME ADVICE?

Thanks in advace.

Re: DEFINING A SOURCE
 

The DEFINE_SOURCE is the correct UDF.

You should obtain the thread of the wall via it's id (visible in boundary condition panel in Fluent). Lookup thread() is the way to obtain it (look Fluent's user Guide). After that you should run a loop over this thread
