For k-e mode, y+ is around 30-300 and for k-w it is around 1. Is that correct? For RSM models based on k-w, the y+ should be around 1 right? And also, for RSM models, based on k-e, y+ should be around 30. Am i correct? In short I want to know, if I am choosing RSM model , BSL and Linear Pressure Strain, what will be the y+ values and wall funtions? Should i choose standard or scalable wall functions?&nbsp; thanks, any help is appreciated.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-436121","topic","type-topic","status-answered","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["436121"],"_bbp_subscription":["296506","466482"],"_bbp_author_ip":["129.11.145.115"],"_bbp_last_reply_id":["436258"],"_bbp_last_active_id":["436258"],"_bbp_last_active_time":["2025-07-08 08:07:41"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["296506","466482"],"_btv_view_count":["138"],"_bbp_topic_status":["answered"]},"test":"scaboleeds-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/436121","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/436121\/revisions"}],"predecessor-version":[{"id":436380,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/436121\/revisions\/436380"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=436121"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
