Contact given is &#8216;Permanently bonded contact&#8217;&nbsp;among all contact pairs as bonded contact default yields a warning which says, &#8220;Bonded contact default and Conducting non-slip wall is found on the same surface&#8221;. <\/p>\n<p> On thermal analysis, I get a max temp as 81.71 degC when h = 8 W\/m2degC. While running CHT analysis, the results go haywire which is of order of 4e35degC. <\/p>\n<p> Please find the model attached herewith and kindly let me know the possible workaround to solve the same. <\/p>\n<p> <a href=\"https:\/\/kaizenat-my.sharepoint.com\/:u:\/p\/prathap\/EQoi4F4FNylNvcwptPS19MUBI8Rnajwkne6Mjfl7J4-GDw?e=R1XKTx\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">https:\/\/kaizenat-my.sharepoint.com\/:u:\/p\/prathap\/EQoi4F4FNylNvcwptPS19MUBI8Rnajwkne6Mjfl7J4-GDw?e=R1XKTx<\/a> <\/p>\n","protected":false},"template":"","class_list":["post-254498","topic","type-topic","status-closed","hentry","topic-tag-ansys-discovery","topic-tag-fluid-solid-heat-transfer-3"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["44791"],"_bbp_likes_count":["0"],"_btv_view_count":["302"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["254498"],"_bbp_forum_id":["27789"],"_bbp_engagement":["202","44791"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["260949"],"_bbp_last_active_id":["260949"],"_bbp_last_active_time":["2021-07-24 13:37:14"]},"test":"prathapkaizenat-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/254498","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\/254498\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=254498"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
