On the user guide, the following is reported: &quot;With this approach, the coupled fluid \/ solid interface is replaced by boundary conditions: the temperature boundary condition from the solid zones is then assigned to the fluid domain, while the heat flux boundary condition from the fluid zones are assigned to the solid zones&quot;. However, it is not handled automatically since when I activate this function, the solid boundary condition at the fluid \/ solid interface switches to an adiabatic condition (heat flux=0) whereas the fluid one switches to a constant temperature condition (300 K as default).<\/p>\n<p>How can I assign the right boundary conditions (temperature from the solid zones assigned to the fluid domain and the heat flux from the fluid zones assigned to the solid domain)<\/p>\n<p>Thank you in advance for your help.<\/p>\n<p>Best regards,<\/p>\n<p>Simone<\/p>\n","protected":false},"template":"","class_list":["post-159503","topic","type-topic","status-closed","hentry","topic-tag-conjugate-heat-transfer","topic-tag-fluent","topic-tag-heat-transfer","topic-tag-transient-analysis"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["2858"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["159503"],"_bbp_forum_id":["27792"],"_bbp_engagement":["25","203014"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["182303"],"_bbp_last_active_id":["182303"],"_bbp_last_active_time":["2021-06-16 13:43:14"]},"test":"simone-paccatihtc-unifi-it"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/159503","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\/159503\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=159503"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
