While comparing my simulation with a colleague&#8217;s results, I saw severe underprediction of TKE generation in my shear regions. I plotted production of k which seems to be fine, however the dissipation is probably too high. Is the fix more mesh-related or a turbulence model issue? Im using k-omega sst with default settings except production limiter is turned off and viscous heating and corner flow correction are turned on.&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/13-07-2026-1783969164-mceclip5.png\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/13-07-2026-1783968973-Screenshot 2026-07-13 095939.png\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/13-07-2026-1783968993-Screenshot 2026-07-13 100039.png\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/13-07-2026-1783969018-Screenshot 2026-07-10 140223.png\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/13-07-2026-1783969130-mceclip2.png\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/13-07-2026-1783969130-mceclip3.png\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/13-07-2026-1783969130-mceclip4.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-461286","topic","type-topic","status-publish","hentry","topic-tag-k-omega-sst","topic-tag-shear","topic-tag-tke-2"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["461286"],"_bbp_subscription":["709287","8124"],"_bbp_author_ip":["128.146.134.132"],"_bbp_last_reply_id":["461375"],"_bbp_last_active_id":["461375"],"_bbp_last_active_time":["2026-07-15 13:40:50"],"_bbp_reply_count":["6"],"_bbp_reply_count_hidden":["1"],"_bbp_voice_count":["2"],"_bbp_engagement":["709287","8124"],"_btv_view_count":["40"],"_bbp_topic_status":["unanswered"]},"test":"pablobhsgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/461286","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\/461286\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=461286"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
