In Fluent is the DEFINE_SOURCE UDF applied to each cell in the cell zone?
I have question regarding the DEFINE_SOURCE UDF. I want to apply a mass source to my model. When hooking a source function to a cell zone, is the source term then calculated and applied for each individual cell in cell zone or is a mean value from all cells applied to selected cell zone?
From the manual (Customization Manual Part I Chapter 184.108.40.206. "The solver passes to the DEFINE_SOURCE term UDF all the necessary variables to define a custom source term, since source terms are solved on a cell basis") I suggest, that the source term is calculated an applied for each cell individual, am I right with this?
Thank you for your help!
