Pictures may help.&nbsp;&lt;\/p&gt;&lt;p&gt;The mass flow outlet was removed for some multiphase several versions back as it wasn&#8217;t stable. The issue is that if we remove x kg\/s and there is a variable amount of a denser phase that the pressure on the boundary becomes unstable. A volume flow boundary (velocity) would be numerically better and potentially physically more sensible as pumps etc suck volume.&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-395520","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/395520","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/395520\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=395520"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
