The structure all have the sample diameter (0.5m) and domain (5m x 15m).<\/p>\n<p>The smooth cylindrical body gave an expected plot showing the lift and drag curve but the other structures didn&#8217;t. I don&#8217;t know if i am correct or not as i am relative new in fluent with respect to this.<\/p>\n<p>For the smooth structure, i used the edge sizing and inflation mesh (inflation option: First inflation layer thickness, first layer height: 0.03m, Maximum layer: 40 and growth rate: 2.5). I applied the same mesh to the other structures but i don&#8217;t know if the result i am having are good.<\/p>\n<p>Please i need advise on the best mesh methods and other settings to achieve a good result on the other structures.<\/p>\n<p>Below are my contour plots for the structure.<\/p>\n<p>SMOOTH STRUCTURE<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/10-04-2024-1712744107-smooth.png\" alt=\"\"><\/p>\n<p>CACTUS SHAPED<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/10-04-2024-1712744182-cactus.png\" alt=\"\"><\/p>\n<p>HORN-STRAKED<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/10-04-2024-1712744213-horn-straked.png\" alt=\"\"><\/p>\n<p>HELICAL-STRAKED<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/10-04-2024-1712744245-helical-strake.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-361494","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["52342","199"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["167"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["361494"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","52342"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["361656"],"_bbp_last_active_id":["361656"],"_bbp_last_active_time":["2024-04-11 08:32:57"]},"test":"kingdsystemsgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/361494","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\/361494\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=361494"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
