I have a couple pictures attached below. The model was made in SolidWorks and seems clean enough, I&#8217;ve been trying to use the SpaceClaim &#8220;fill&#8221; function to model a solid for the air in the room with no success. I&#8217;ve assumed it&#8217;s because of the fact that the vents stretch across the room preventing the fill function from executing properly but I&#8217;m unsure. To circumvent this, I modeled extra bodies in the CAD software but when it came to meshing, the mesh failed due to too much memory being needed (the model has a lot of extra extrusions to accommodate all the space; a lot of failure points could be responsible)&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>On a side note, this particular room, even when ran without any air modeling, has a really unstable mesh. Any meshing practices that would be recommended for a model like this would be greatly appreciated.<\/p>\n<p>Model itself w\/o any extra extrusions:<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/07\/26-07-2023-1690380519-mceclip2.png\"><\/p>\n<p>Mesh:&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/07\/26-07-2023-1690380787-mceclip3.png\"><\/p>\n","protected":false},"template":"","class_list":["post-294929","topic","type-topic","status-closed","hentry","topic-tag-ansys-cfd-1","topic-tag-cfd-fluent","topic-tag-fill-1","topic-tag-meshing"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["2730","199"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["2164"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["294929"],"_bbp_forum_id":["27790"],"_bbp_engagement":["199","2730"],"_bbp_voice_count":["2"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["295075"],"_bbp_last_active_id":["295075"],"_bbp_last_active_time":["2023-07-27 07:43:00"]},"test":"btdonov2ncsu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/294929","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\/294929\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=294929"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
