For a momentum under a relaxation factor of 0.0001, the residual of the continuity equation is in order of  e-5. Can you tell me whether using a momentum factor of 0.0001 is logical or not? I notice a sharp decrease of residual after decreasing momentum factor. This is why I reduced the momentum factor to 0.0001 to reduce continuity residual.  Can I trust this simulated result?<br \/>\nOr, is there any restriction on reducing under relaxation factor?<br \/>\nRegards<br \/>\nAnadi<br \/>\n<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/417\/A6CVMJJQL2C5.png\" width=\"\" height=\"\" \/><\/p>\n","protected":false},"template":"","class_list":["post-169655","topic","type-topic","status-closed","hentry","topic-tag-ansys-fluent","topic-tag-convergence","topic-tag-error","topic-tag-fluid-dynamics","topic-tag-fluid-flow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["4433"],"_bbp_likes_count":["0"],"_bbp_subscription":["232243"],"_bbpmt_movedon":["2022-08-26 07:06:46"],"_bbpmt_movedfrom":["27819"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["169655"],"_bbp_forum_id":["27792"],"_bbp_engagement":["16400","185601"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["215198"],"_bbp_last_active_id":["215198"],"_bbp_last_active_time":["2022-05-24 13:42:39"]},"test":"anadi"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/169655","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\/169655\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=169655"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
