The boundary conditions were 4m\/s inlet velocity, 0.9 volume fraction (vf) gas and 0.1 water vf, all introduced at the inlet, with no slip walls. The simulation was initialised using the phase-scheme pressure coupling, having set the momentum, k-epsilon and vf to second-order, second-order and first-order (upwind) respectively. However, during simulation run, the continuity residual never converges but always give rise to a residual value of e-2 at the end of the iterations value. My query is which technique or approach is recommended in order for the continuity residual to converge ?, mind you I have a well refined mesh occupying an orthogonality value above 0.1 and skewness less than 0.9. Kindly assist me with this case of mine.&nbsp;<\/p>\n<p>Thanks,<\/p>\n<p>Edward<\/p>\n","protected":false},"template":"","class_list":["post-350863","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["225272","15180"],"_bbp_author_ip":["23.206.193.41"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["172"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["350863"],"_bbp_forum_id":["27792"],"_bbp_engagement":["15180","225272"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["351569"],"_bbp_last_active_id":["351569"],"_bbp_last_active_time":["2024-02-15 04:34:41"]},"test":"edward-obianaghahud-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/350863","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\/350863\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=350863"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
