I was wondering if there is a way to retrieve values from a named expression (new Fluent feature) in a UDF. The species transport equation in my model has a special convection term that depends on the gradient of a certain potential. Because this potential varies only with respect to the coordinates, I can compute it from Named Expressions. Is there a way to retrieve these values later from a UDF (so I can calculate its gradient at the faces)? Other people working in this project may review/edit this potential, and it would be much easier to do so via the regular Fluent interface.
Thanks in advance!
