So basically for 1.8 mm and 1.6 mm the residual error drops below 1e-3 easily. But when making the global mesh further refined to around 1.2,1.4 mm the residual finds it hard to drop below 1e-3. But the results converge in the monitor plots to decent values comparable to literature work. The mesh metrics are also good , anything I need to think about to get the residual tolerance better&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-366533","topic","type-topic","status-closed","hentry","topic-tag-fluent-ansys-1","topic-tag-heat_exchanger-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["281119","62293"],"_bbp_author_ip":["23.216.133.166"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["352"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1715494692:213352"],"_bbp_topic_id":["366533"],"_bbp_forum_id":["27792"],"_bbp_engagement":["62293","281119"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["366718"],"_bbp_last_active_id":["366718"],"_bbp_last_active_time":["2024-05-14 07:21:40"]},"test":"20625409student-curtin-edu-au"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/366533","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/366533\/revisions"}],"predecessor-version":[{"id":366534,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/366533\/revisions\/366534"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=366533"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
