It is a 3D wing geometry for external aerodynamics analysis. In the past, I had some success with a mesh made of tetrahedral elements only, but now that I must increase the fluid domain size drastically, tetra elements would result in such a large mesh that it would be prohibitive. I have seen many examples for similar problems, but they either use ICEM for meshing (which I do not have access to) or just use tetrahedral elements in a very small fluid domain (which does not help my case here). So the challenge is to use Ansys Workbench Meshing for this.<\/p>\n<p>So right off the bat, I have &quot;cleaned&quot; and decomposed the geometry into sweepable bodies, according to this Ansys Tutorial series that someone here recommended (Thanks!) <a href=\"https:\/\/www.youtube.com\/watch?v=P19GOTQWmc0&amp;t=95s\" rel=\"nofollow\">https:\/\/www.youtube.com\/watch?v=P19GOTQWmc0&amp;t=95s<\/a><\/p>\n<p>It resulted in the following sweepable bodies:<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/798\/9ONHCJKSQV64.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/798\/9ONHCJKSQV64.jpg\" alt=\"sweepable bodies.jpg\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-54295","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["26625"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["??q)"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["3893"],"_bbp_subscription":["233367"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["54295"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","22555","187545"],"_bbp_voice_count":["3"],"_bbp_reply_count":["16"],"_bbp_last_reply_id":["150952"],"_bbp_last_active_id":["150952"],"_bbp_last_active_time":["2021-04-27 15:25:06"]},"test":"dioser"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/54295","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\/54295\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=54295"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
