I am using a multi-fluid VOF hybrid model with the interface defined sharp\/dispersed.&lt;\/p&gt;&lt;p&gt;How does the simulaiton define where a disperse phase is present\/created and how do I prevent it from smearing by having droplets everywhere.&lt;br&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/08\/25-08-2025-1756115910-mceclip0.png\" \/>&lt;br&gt;Hopefully you understand what I mean by this, I will gladly explain more.&lt;br&gt;Kind regards,&lt;br&gt;Jasper&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-440057","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["440057"],"_bbp_subscription":["553167","199","23673"],"_bbp_author_ip":["131.155.24.22"],"_bbp_last_reply_id":["440482"],"_bbp_last_active_id":["440482"],"_bbp_last_active_time":["2025-09-01 11:01:38"],"_bbp_reply_count":["16"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["3"],"_bbp_engagement":["553167","199","23673"],"_btv_view_count":["418"],"_bbp_topic_status":["unanswered"]},"test":"j-j-a-v-zutphenstudent-tue-nl"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/440057","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\/440057\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=440057"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
