With the appropriate local sizings I am able to achieve a good quality surface mesh, by &#8220;good&#8221; I mean from both visual inspection and quantitatively (skewness &lt; 0.6 everwhere).&lt;\/p&gt;&lt;p&gt;However when I generate the volume mesh I get a very low volumetric mesh quality (orthogonal quality &lt; 1e-2 for a lot of cells) almost everywhere on the wing. I get a very bad quality when I add the boundary layer refinement that I want (first layer thickess = 1 micrometer) and I noticed that the smaller the first layer thickness, the lower is the quality. Inserting an &#8220;Improve volume mesh&#8221; task does not lead to improvements. Furthermore I don&#8217;t get any Geometry Errors\/warnings.&lt;\/p&gt;&lt;p&gt;Does someone have any experience with that? Some suggestions to improve the mesh?&nbsp;&lt;\/p&gt;&lt;p&gt;Thanks in advance.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-437008","topic","type-topic","status-publish","hentry","topic-tag-fluent-ansys-1","topic-tag-3d-meshing","topic-tag-3d-wing-1","topic-tag-fluent","topic-tag-fluent-mesh","topic-tag-fluentmesh-1","topic-tag-fluentmeshing-1","topic-tag-meshing"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27796"],"_bbp_topic_id":["437008"],"_bbp_subscription":["503048","13659"],"_bbp_author_ip":["62.218.164.126"],"_bbp_last_reply_id":["437135"],"_bbp_last_active_id":["437135"],"_bbp_last_active_time":["2025-07-17 15:27:51"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["503048","13659"],"_btv_view_count":["968"],"_bbp_topic_status":["unanswered"]},"test":"ciro-cuozzoait-ac-at"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/437008","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\/437008\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=437008"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
