I am simulating flow through a porous medium using ANSYS Fluent. There is only one inlet and no outlet. However, when I view the CFD Post, I realize that the values for mass flow rate are all negative. This is strange to me because the vectors show that the flow is in the positive x direction as I&#8217;d set it up. Why are my mass flow rate values negative?<\/p>\n","protected":false},"template":"","class_list":["post-301664","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["286812","199"],"_bbp_author_ip":["96.7.218.215"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1052"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["301664"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","286812"],"_bbp_voice_count":["2"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["301699"],"_bbp_last_active_id":["301699"],"_bbp_last_active_time":["2023-08-16 13:15:45"]},"test":"o-fabunmitees-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/301664","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\/301664\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=301664"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
