A promblem of UDM macro
hello! I want to store the variable valus of "incident radiation" using UDM macro, but i found that there is no such macro correspond to the variable of "incident radiation" in the Fluent UDF manual. Is there any idea about how to store the "incident radiation" variable? thanks!

Any variable - basic or derived can be stored into UDM. You have to derive the expression for incident radiation. If this is a boundary condition then you need to use UDS for which you may or may not require to solve transport equation.

Best wishes
