It&#8217;s a transient simulation and the solution is converging at every time step. As you can see, residuals are not changing at all with number of iterations. How can I know if the solution is converged? I searched for similar query in forum but the answers are not very satisfactory or explanatory. It will be helpful if anyone can shed some light on the problem of convergence.<\/p>\n<p>Thanks.<img decoding=\"async\" title=\"Residuals\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/17-08-2023-1692267382-fc35eee7242345e3362c8ed1a86d23e4.jpg\" alt=\"Simulation residual monitor\"><\/p>\n","protected":false},"template":"","class_list":["post-301877","topic","type-topic","status-closed","hentry","topic-tag-convergence","topic-tag-k--turbulence-model-1","topic-tag-transient"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["499","8124"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1662"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["301877"],"_bbp_forum_id":["27792"],"_bbp_engagement":["499","8124"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["301904"],"_bbp_last_active_id":["301904"],"_bbp_last_active_time":["2023-08-17 12:34:46"]},"test":"vasanthg"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/301877","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\/301877\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=301877"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
