I have a problem with meshing a 3D iced wing with Fluent Meshing.&lt;\/p&gt;&lt;p&gt;The CAD import, sizings and surface mesh complete successfully, while if I use a lower number of layers for boundary layer (around 15) everything completes successfully, while if I increase the number of layers (around 25) the volume mesh process gets stuck at around 70-80%, even if the layers generation has completed. I am quite sure it is not a problem of computational resources as the mesh generation with 15 layers completes in more or less 4 minutes, while I also tried to leave the PC running the whole night to generate the mesh with 25 layers and there were no advancements.&lt;\/p&gt;&lt;p&gt;These are the last lines i get in the console (when it gets stuck I always get the same last lines, it always happens after Merging domains&#8230; Done. ):&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/04\/24-04-2025-1745484199-mceclip0.png\" \/>&lt;\/p&gt;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;PS: this problem happens on 2025R1, haven&#8217;t tried other versions&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-429882","topic","type-topic","status-publish","hentry","topic-tag-fluent-cfd-ansys-1","topic-tag-ansys-fluent-meshing-1","topic-tag-fluent-mesh","topic-tag-meshing"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27796"],"_bbp_topic_id":["429882"],"_bbp_subscription":["503048","199"],"_bbp_author_ip":["62.218.164.126"],"_bbp_last_reply_id":["430009"],"_bbp_last_active_id":["430009"],"_bbp_last_active_time":["2025-04-25 09:07:20"],"_bbp_reply_count":["3"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["503048","199"],"_btv_view_count":["1096"],"_bbp_topic_status":["unanswered"],"_edit_last":["503048"],"_bbp_revision_log":["a:1:{i:429884;a:2:{s:6:\"author\";i:503048;s:6:\"reason\";s:0:\"\";}}"],"_edit_lock":["1745486200:503048"]},"test":"ciro-cuozzoait-ac-at"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/429882","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\/429882\/revisions"}],"predecessor-version":[{"id":429884,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/429882\/revisions\/429884"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=429882"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
