However, I am encountering issues with maintaining an appropriate <em>y+<\/em> value.&lt;\/p&gt;&lt;p&gt;As I am using the k-omega SST turbulence model, it&#8217;s essential to achieve a <em>y+<\/em> value of 1 or less. For a <em>y+<\/em> value of 1 in my case, the corresponding wall-normal spacing (<em>y<\/em>) should be 2.34e-5. Despite increasing the number of elements along various edges of the mesh, the maximum <em>y<\/em> value I can achieve is 5 e-4.&lt;\/p&gt;&lt;p&gt;Is there a way to reach the required <em>y<\/em> value without using inflation layers, as I am working with a structured mesh?&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/18-09-2024-1726673038-B.JPG\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/18-09-2024-1726672849-C.JPG\" alt=\"\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/18-09-2024-1726672996-A.JPG\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-383024","topic","type-topic","status-publish","hentry","topic-tag-Structuredmeshing-2","topic-tag-2d-airfoil","topic-tag-fluent","topic-tag-student-version","topic-tag-turbulence-model"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["54550","199"],"_bbp_author_ip":["197.153.67.35"],"_btv_view_count":["257"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["383024"],"_bbp_forum_id":["27790"],"_bbp_engagement":["199","54550"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["383032"],"_bbp_last_active_id":["383032"],"_bbp_last_active_time":["2024-09-18 16:11:06"]},"test":"jinane-radietu-uae-ac-ma"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/383024","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\/383024\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=383024"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
