I am also not sure if I am supposed to define the walls of the enclosure as &#8216;symmetry&#8217;.&nbsp; My largest hurdle is creating an air input.&nbsp; Currently, I have a line that enters the top and exits in the middle of the case.&nbsp; i can do a volume extract on that line and define the Airin and Airout, but when I do a volume mesh they get lost since the air line is inside the enclosure.&nbsp; Is there a way to define a point source for an air exit?&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/09\/04-09-2025-1757023518-mceclip1.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-440814","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["440814"],"_bbp_author_ip":["136.226.98.177"],"_bbp_last_reply_id":["441043"],"_bbp_last_active_id":["441043"],"_bbp_last_active_time":["2025-09-09 09:25:26"],"_bbp_reply_count":["4"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["3"],"_bbp_engagement":["72736","199","15180"],"_btv_view_count":["19589"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["199","15180","72736"]},"test":"andrew-m-hayeslmco-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/440814","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\/440814\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=440814"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
