The fin is made of aluminum and has a free air stream at 298.16 K. The fin&#8217;s tip temperature will vary with time. So, the convective heat transfer coefficient will also vary. Hence, convection heat transfer will also vary.<\/p>\n<p>The equation in the photo wanted to be written in the convective heat transfer boundary condition. Using UDF or named expression, anything is possible.<\/p>\n<p>I am thanking you! <img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/12\/09-12-2022-1670610032-Screenshot 2022-12-09 234902.png\" alt=\"\" width=\"333\" height=\"98\"><img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/12\/09-12-2022-1670610115-Screenshot 2022-12-09 234818.png\" alt=\"\" width=\"274\" height=\"439\"><\/p>\n","protected":false},"template":"","class_list":["post-243603","topic","type-topic","status-closed","hentry","topic-tag-2d-heat-transfer-2","topic-tag-boundary-conditions","topic-tag-conjugate-heat-transfer","topic-tag-convection-coefficient","topic-tag-heat-transfer-coefficient","topic-tag-named-expressions","topic-tag-udf"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["270209","15180"],"_bbp_author_ip":["96.7.74.173"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1730"],"_bbp_likes_count":["1"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["243603"],"_bbp_forum_id":["27792"],"_bbp_engagement":["15180","270209"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["243929"],"_bbp_last_active_id":["243929"],"_bbp_last_active_time":["2022-12-13 13:59:39"]},"test":"p21td006med-svnit-ac-in"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/243603","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\/243603\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=243603"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
