I am using &quot;Thermal Element (PLANE55)&quot;, which is available in ANSYS 18. The left side has fixed Temperature of 200 degree C. The right side has &quot;Convection&quot;.<\/p>\n<p>I am interested to calculate the &quot;<strong>heat<\/strong>&quot; that is required to maintain &quot;200 degree C&quot; at the &quot;Left Side&quot;. So, I selected the nodes where &quot;Boundary Condition&quot; was applied. Then, I am using &quot;PRNLD, Heat&quot; command. It offers me &quot;Total Heat&quot;. However, it comes with a &quot;<strong>Negative Sign<\/strong>&quot;. <\/p>\n<p>What is the physical meaning of this &quot;<strong>Negative Sign<\/strong>&quot;? Is it related to &quot;Thermal Equilibrium&quot;. Could you explain. I am also attaching my code. Many, many thanks,<\/p>\n<p>Awlad.<\/p>\n<div data-embedjson=\"{&quot;url&quot;:&quot;https:\/\/us.v-cdn.net\/6032193\/uploads\/WHWIP9YBVWJR\/composite-wall-thermal-simulation.txt&quot;,&quot;name&quot;:&quot;Composite_Wall_Thermal_Simulation.txt&quot;,&quot;type&quot;:&quot;text\/plain&quot;,&quot;size&quot;:1565,&quot;embedType&quot;:&quot;file&quot;}\">\n<a href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/WHWIP9YBVWJR\/composite-wall-thermal-simulation.txt\" download aria-label=\"Composite_Wall_Thermal_Simulation.txt\"><br \/>\nComposite_Wall_Thermal_Simulation.txt<br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-51659","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["23932"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["I?||"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["602"],"_bbp_subscription":["237700"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["51659"],"_bbp_forum_id":["27791"],"_bbp_engagement":["3599","20905"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["140396"],"_bbp_last_active_id":["140396"],"_bbp_last_active_time":["2021-01-28 20:52:25"]},"test":"awlad"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/51659","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\/51659\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=51659"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
