The case is a compressible nozzle. In the tutorial, mass flow rate of the domain is reported and convergece is obviously reached. However, when I checked the total heat transfer rate report, the net results is -22.4997W.&nbsp; The case is surely converged since I followed every steps in tutorial and all results are exactly the same with tutorial. I just can&#8217;t understand why the total heat transfer rate of the system is not close to zero when the case is converged.<\/p>\n<p><\/p>\n<p>I put the screen shot of temperautre contour and heat transfer rate flux reports below.&nbsp; I wonder are there any special reasons with which total heat transfer rate doesn&#8217;t have to be zero when cases are converged.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/adcf4c26-90bb-40b4-94b1-a8b200eed389\/1858be7d-96fd-4abe-8833-abfe002631e8_qq??20200720101457.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/adcf4c26-90bb-40b4-94b1-a8b200eed389\/e4875cdb-620f-4198-9eee-abfe00263e32_qq??20200720101524.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>Best regards<\/p>\n<p><\/p>\n<p>Weiqiang<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-46302","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["18485"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["842"],"_bbp_subscription":["236081"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["46302"],"_bbp_forum_id":["27792"],"_bbp_engagement":["22555","156533"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["121846"],"_bbp_last_active_id":["121846"],"_bbp_last_active_time":["2020-07-20 09:23:41"]},"test":"weiqiang-liu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/46302","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\/46302\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=46302"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
