Originally I had set the problem up such that I had 40W of heat leaving the surface of that body. As a test, I changed the boundary condition for that body to be a heat generation boundary condition with the W\/m^3 set such that that body was generating 40W of heat. I received very different values for the temperature distribution and heat fluxes. I am confused as to why they are different. I would imagine that if the body was generating 40W of heat, it would also be releasing 40W of heat to the other bodies as well. Which boundary condition would be correct to use for this problem? n<\/p>\n","protected":false},"template":"","class_list":["post-47230","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["19429"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["H??:"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["2068"],"_bbp_subscription":["79935"],"_bbpmt_movedon":["2022-08-26 07:35:21"],"_bbpmt_movedfrom":["27819"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["47230"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","176278"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["123984"],"_bbp_last_active_id":["123984"],"_bbp_last_active_time":["2020-08-11 08:48:41"]},"test":"jonahbt40"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/47230","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\/47230\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=47230"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
