HI there, I am currently doing my masters thesis on Open Source Free or low cost CFD software and running some benchmarks.
The one benchmark that I am very interested in using is the Non-Newtonian Flow Through Expansion Channel as seen in your validation cases and documentation. I have one simply query which may sound silly but myself and a few other student have not managed to work i out yet. What is the U value in “Ux/U” for the following picture
and how was it worked out. I have downloaded this exact case from the project file and have i open in paraview but cant seem to figure out what it is, many many options have been explored. The research paper attached to the validation case also did not say. ANY HELP will be a HUGELY appreciated.
