FLUENT energy source UDF formulation

Hello all,

I was wondering if anyone can help me with FLUENT's energy source definition.

I am using another UDF to extract the radiation information for a face of a thread. This information needs to be used in an internal calculation (basic scalar arithmetic), and must be returned as a source. The trouble is that the source macro, DEFINE_SOURCE, uses cell information. Does anyone know how to utilize radiation information for a face in a source term that is defined on a cell?

Thanks
