Its definition is almost the same as the quality confirmation type in GAMBIT, Equi Size Skew. You can also check this with Fluent and select Equi Size Skew (cell value) in the Contour panel.  The skewness in ANSYS Meshing evaluates to what extent the edge and angle of the created mesh deviates from the ideal state (equilateral triangle \/ square) and is defined as follows.  \u2022(Ideal Cell Size \u2013 Created Cell Size) \u00f7 Ideal Cell Size oIdeal cell size = equilateral cell size with radius of the same circumcircle oApplies to triangular and tetrahedral meshes     \u2022max[(\u03b8max \u2013 \u03b8e) \/ (180 \u2013 \u03b8e), (\u03b8e \u2013 \u03b8min) \/ \u03b8e] o\u03b8max = face\u2019s or cell\u2019s maximum angle  o\u03b8min = face\u2019s  or cell\u2019s minimum angle o\u03b8e = face\u2019s  or cell\u2019s ideal angle (equiangle\u2014equilateral triangle: 60 degrees, square: 90 degrees) oApplies to all mesh types oSame defining formula as Equi Size Skew in GAMBIT <\/p>\n<p>Attachments:<br \/>\n1. <a href=https:\/\/ansys13.ansys.com\/KnowledgeArticles\/Phase-3\/2048443\/2048443.pdf>2048443.pdf<\/a><\/p>\n","protected":false},"template":"","class_list":["post-179354","topic","type-topic","status-publish","hentry","topic-tag-17-2","topic-tag-fluid-dynamics","topic-tag-general","topic-tag-meshing"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"siebel_km_number":["2048443"],"_bbp_last_active_time":["8\/25\/2023 20:20"],"_bbp_forum_id":["27796"],"_bbp_author_ip":["23.56.168.180"],"application_name":["Meshing"],"family":["Fluid Dynamics"],"km_published_date":["2017-02-23T00:00:00.000Z"],"product_version":["17"],"_btv_view_count":["29714"],"_edit_lock":["1705047985:80072"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/179354","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/179354\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=179354"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
