Help needed for defining an source term utilizing face information
 
Hello all,

I am hoping to define an energy source term for my model. The source is a balance of radiation and some other information. The issue is that the radiation information can only be extracted from the face (as far as I know, since it is a flux quantity), while the source term can only be added to the cells. Does anyone know how I can use face information in a cell-based macro?

Thanks

hai
if the data is from the face, you can extract that data form the face usign a udf for face and use the value in cell again through udf. i am not sure about what u r doing and i feel this helps

with regards

Yes, that is the concept I was unsure about, specifically in the implementation stages (FLUENT macro use).
