Hi, I am new to Ansys, and I want to analyze the flow inside a closed channel. What I want to check is to see how the fluid is distributed within the channel -whether there are locations or volumes inside the channel where the fluid won't reach, and I would also like to quantify it between different channel geometries for the same boundary conditions. ChatGPT told me about the flow uniformity index. I would like to know if it is the right parameter or if there are better ones in Fluent.
In Fluent, I also found that there are two different types of uniformity index—area-weighted and mass-weighted. I would like to know the difference between them and also find out which will be better suited to me (it's a different value for both area-weighted and mass-weighted).

Have a look in the Fluent User's Guide, Chapter 43.4 lists all of the variables. Elsewhere you'll find definitions for area, mass weighted and the other reports. 

It's not how I'd do it, I'd use the scalar approach mentioned elsewhere. 

Moderator comment (note comment, not warning) if you create one longer post to describe what you're wanting to do, and how you think you can do it, it's easier to comment into a single thread. With three threads we could answer each one, and give conflicting advice whilst having answered each post "correctly".

Hi, thanks for the reply. Can you share with me the user guide? Is there a link for me to get it?

Seriously?!? You've not tried the ? button in Fluent?
