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&#8217;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.&lt;br&gt;In Fluent, I also found that there are two different types of uniformity index&mdash;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&#8217;s a different value for both area-weighted and mass-weighted).&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-453937","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["453937"],"_bbp_subscription":["438440","199"],"_bbp_author_ip":["49.37.234.76"],"_bbp_last_reply_id":["454155"],"_bbp_last_active_id":["454155"],"_bbp_last_active_time":["2026-03-11 09:50:18"],"_bbp_reply_count":["3"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["438440","199"],"_btv_view_count":["37"],"_bbp_topic_status":["unanswered"]},"test":"ad40ac3a73e2fa5a7b99657c3f96c2cacdf6b975"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/453937","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/453937\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=453937"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
