As shown in image that the Ui plane is 10mm inside porous media and at the periphery there is a wall BC of no slip type and numerical value of Ui is calculated under surface integral area weighted which is shown in image.<\/p>\n<p>Query:<br \/>As shown in image the minimum velocity is 0 at the wall. so do i need to take the plane few mm inside from the wall in order to avoid zero velocity or is it ok from physics point of view.<br \/>kindly let me know what is the best way to post process uniformity index value: with wall plane or without wall plane<\/p>\n<p>thanks<\/p><\/div>\n<div class=\"ps-post__attachments ps-stream-attachments ps-js-activity-attachments js-stream-attachments\">\n<div class=\"ps-post__attachment cstream-attachment photo-attachment\">\n<div class=\"ps-post__gallery ps-media-photos ps-media-grid ps-post__gallery--single ps-media-grid--single ps-clearfix\" data-ps-grid=\"photos\">\n<div class=\"ps-media-grid-padding\">\n<div class=\"ps-media-grid-fitwidth\"><img decoding=\"async\" src=\"https:\/\/community.ansys.com\/wp-content\/peepso\/users\/47674\/photos\/thumbs\/f73c4e9858a6b8ef7e803676a1474450_l.jpg\" data-ajax-id=\"47674\" data-ajax-dir=\"users\" data-ajax-file=\"f73c4e9858a6b8ef7e803676a1474450\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"template":"","class_list":["post-275828","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["279876","199"],"_bbp_author_ip":["23.192.164.18"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["2107"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["275828"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","279876"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["275834"],"_bbp_last_active_id":["275834"],"_bbp_last_active_time":["2023-03-22 09:47:24"]},"test":"amit-gulavaniecocatindia-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/275828","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\/275828\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=275828"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
