I have different sizing on the faces and edges of the vertical plates compared to the horizontal plates.&nbsp; The intention is to have a finer mesh around the corners of the vertical plates causing separation, coarser on the horizontal faces.<\/span><\/p>\n<p><span style=\"font-size: 12pt\">Where the vertical plates meet the horizontal plates there is an automatic mesh refinement of the corner zone as expected &#8211; see P2. The view here is underside of top horizontal plate.<\/span><\/p>\n<p><img decoding=\"async\" title=\"P2\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/12-04-2024-1712901320-p2.PNG\" alt=\"\"><\/p>\n<p>The problem I have is that this refinement is reflected onto the top surface of the upper plate &#8211; see P3.<\/p>\n<p><img decoding=\"async\" title=\"P3\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/12-04-2024-1712901429-P3.PNG\" alt=\"\"><\/p>\n<p><span style=\"font-size: 12pt\">One issue with this is it increases the overall mesh size for the problem &#8211; especially when inflation layers are added.<\/span><\/p>\n<p><span style=\"font-size: 12pt\">However my main concern is the transition between the coarse mesh to fine then back again along the top flow surface &#8211; the mesh does not look good, which makes me concerned about quality of simualtion. &#8211; See P4, P5 and P6. I have used poly-hexcore.<\/span><\/p>\n<p><img decoding=\"async\" title=\"P4\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/12-04-2024-1712901848-P4.PNG\" alt=\"\"><\/p>\n<p><img decoding=\"async\" title=\"P5\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/12-04-2024-1712901869-P5.PNG\" alt=\"\"><\/p>\n<p><img decoding=\"async\" title=\"P6\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/12-04-2024-1712901901-P6.PNG\" alt=\"\"><\/p>\n<p><span style=\"font-size: 12pt\">Does anyone have a suggestion how I can fix this so that the top face has consistent larger size alomng full length (with exception of edge transition zones?)<\/span><\/p>\n<p><span style=\"font-size: 12pt\">Thanks<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-361873","topic","type-topic","status-closed","hentry","topic-tag-fluent","topic-tag-mesh","topic-tag-mesh-refinement","topic-tag-meshing","topic-tag-watertight-workflow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["343525","199"],"_bbp_author_ip":["23.52.43.16"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["400"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["361873"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","343525"],"_bbp_voice_count":["2"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["362386"],"_bbp_last_active_id":["362386"],"_bbp_last_active_time":["2024-04-16 07:00:26"]},"test":"robert-reisgriffithuni-edu-au"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/361873","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\/361873\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=361873"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
