More specifically, I want to know if the VOF model ever directly touches the primary phase for solving continuity equation?<\/p>\n<p><\/p>\n<p>Also, what does the continuity equation residuals seen in the convergence plot of a vof model solving process indicate? Is the equation solved for a mixture?<\/p>\n<p><\/p>\n<p>I went through the theory manual for knowing exactly which and how many equations are solved in it. However, it&#8217;s pretty confusing as just after introduction, limitations of the VOF model, the next topic on equations starts with Vapor-fraction equation which is nothing but a continuity equation for secondary phase. Then comes momentum and energy equations. It is not understood from the manual is continuity equation is ever solved for primary phase or not.<\/p>\n<p><\/p>\n<p>Thank You.<\/p>\n","protected":false},"template":"","class_list":["post-39873","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["12052"],"_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":["1414"],"_bbp_subscription":["240923"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["39873"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","22555","166253"],"_bbp_voice_count":["3"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["102654"],"_bbp_last_active_id":["102654"],"_bbp_last_active_time":["2020-01-15 15:36:05"]},"test":"soumitra2102"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/39873","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\/39873\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=39873"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
