Hello everyone,

I am trying to write a UDF for the advection term of the transport equation, but am facing some problems since I am quite new to writing UDFs.

I wanted to try this approach: I would like to find the code for the 'default' / built-in Flux Function (named 'mass flow rate' in Fluent), make small changes to it and then import the modified function as a UDF.
(See attached picture: I already imported a UDF from the User Guide, but I would like to import another UDF that is almost identical to the 'mass flow rate'-Flux Function)

Is this possible?

I already searched for .C-files (which could be compiled as a UDF) in the '...\ANSYS Inc' folder (installation path) but I was unable to find the corresponding file.

I am thankful for any advice on this topic
