In this simulation i need high accuracy for flow variables just above the cubes. Also, I&#039;m using k-w sst turbulence model, since it has a good accuracy for both close and far from the walls. After the simulation, y+ values near wall boundaries were way above the recommended value for this turbulence model.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/511\/T570CZGHU8N8.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/511\/T570CZGHU8N8.jpg\" alt=\"mesh1.jpg\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-162530","topic","type-topic","status-closed","hentry","topic-tag-k-omega-sst","topic-tag-meshing","topic-tag-wall-boundary-condition","topic-tag-y-plus"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["2271"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["162530"],"_bbp_forum_id":["27792"],"_bbp_engagement":["25","199","190163"],"_bbp_voice_count":["3"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["193033"],"_bbp_last_active_id":["193033"],"_bbp_last_active_time":["2021-11-08 16:02:43"]},"test":"mohammadsh"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/162530","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\/162530\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=162530"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
