How to implement a 3-element Windkessel model as an outlet BC in Ansys Fluent?

  Hi!
  I am working on fluid dynamics simulations using the latest version of Ansys Fluent. My volume mesh geometry has three boundaries: two are velocity profile inlets, and the third I would like to set as a three-element Windkessel model outlet. I have noticed that Windkessel V3 extension is available for versions 17, 17.1, and 17.2, but it is not compatible with newer versions of Fluent, including the one I currently use. I have read about using UDFs and CEL expressions to integrate the model into Ansys, but the implementation of the model in Fluent was not described in detail.
  
  My question is: how can a lumped model, specifically the three-element Windkessel, be implemented as an outlet in recent versions of Ansys Fluent?
  I would appreciate any help. Thank you in advance.
  
  Any help would be much appreciated. Thank you very much in advance!

  Have a look in the older Windkessels ACTs. You may find some clues buried in what you downloaded.
