Therefore I&#8217;ve chosen the Eulerian Multi Fluid model, with air as phase 1, water as phase 2.&nbsp;<\/p>\n<p><\/p>\n<p>As my boundary condition for the inlet I&#8217;ve chosen a mass flow inlet. I&#8217;ve set 0 kg\/s for air and 12.5 kg\/s for water with a volume fraction of 1.&nbsp;<\/p>\n<p><\/p>\n<p>I&#8217;ve done a initialization from the inlet and the velocity is generated correctly. After the calculation the post-processing shows a mass flow of max 6e-1 kg\/s\/m2 at the inlet instead of the set 12.5 kg\/s (the area is about 0.088 m2, so it should be aroung 143 kg\/s\/m2).&nbsp;<\/p>\n<p><\/p>\n<p>Can anyone tell me how this is possible? Is it not possible to choose a mass flow inlet in a VOF model? Or could there be another reason?&nbsp;<\/p>\n<p><\/p>\n<p>Thanks in advance,&nbsp;<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Regards.&nbsp;<\/p>\n<p><\/p>\n<p>Daniela<\/p>\n","protected":false},"template":"","class_list":["post-32084","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["4256"],"_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","0","0","0","0"],"_btv_view_count":["1752"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["32084"],"_bbp_forum_id":["27792"],"_bbp_engagement":["62","199","22555","161089"],"_bbp_voice_count":["4"],"_bbp_reply_count":["28"],"_bbp_last_reply_id":["72363"],"_bbp_last_active_id":["72363"],"_bbp_last_active_time":["2018-12-13 19:18:30"]},"test":"daniela"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/32084","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\/32084\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=32084"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
