I have followed the SCDM workflow wherein I converted model to Icepak compatible CAD objects. Chassis &amp; fans are different assemblies, did this to define better mesh parameters on fans &amp; for non-conformal meshing. The chassis has perforated incline openings near fans &amp; sections at the end. The way it supposed to work is the air (ambient) gets pushed by fans over to the chassis through these inclined openings and come out the other opposide face (maxX). I have modelled the fan using MRF method with fluid block having RPM of 5000.<\/p>\n<p>However when I try to generate the mesh, I get few warnings like,<\/p>\n<ol>\n<li>Opening &#8220;Opening&#8221;shape (incline) doesn&#8217;t intersect with Component1.<\/li>\n<li>flow and thermal specifications are ignored for internal opening &#8220;Opening&#8221;<\/li>\n<li>No mesh exists for cabinet_default_side_maxx<\/li>\n<\/ol>\n<p>However when I try to run the solver, it says there are no fans or openings in the model. I&#8217;m trying to figure out this issue but any help on this regard would be highly appreciated. <a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/20-04-2023-1682002461-Icepak model_wire.PNG\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/20-04-2023-1682002461-Icepak model_wire.PNG\" alt=\"Icepak model\"><\/a><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/20-04-2023-1682011944-Global mesh w multi level meshing max levels.PNG\" alt=\"Global Meshing settings\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/20-04-2023-1682011989-Assembly mesh_multilevel setting tab.PNG\" alt=\"Component1 Mesh settings\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/20-04-2023-1682012033-Mesh_Z-Axis.PNG\" alt=\"Mesh Z- Cut plane\"><\/p>\n","protected":false},"template":"","class_list":["post-280432","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["23.223.149.174"],"_bbp_subscription":["75303","92143"],"_wp_old_date":["2023-04-19"],"_btv_view_count":["1710"],"_edit_lock":["1682011344:215325"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["280432"],"_bbp_forum_id":["27793"],"_bbp_engagement":["75303","92143"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["281099"],"_bbp_last_active_id":["281099"],"_bbp_last_active_time":["2023-04-25 11:51:21"]},"test":"danny-joseaei-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/280432","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\/280432\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=280432"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
