I want to apply the laser and other heat losses(convection and radiation) at the interface of the gas and the metal. When the laser melts the solid, the surface deforms and the interface location changes continuously. For this, I need to track the interfacial cells continuously at every iteration. The interfacial cells will have a volume fraction of the secondary phase in a given range(say 0.05 to 1) but this value changes in the cells at every iteration due to melting. <\/p>\n<p>I am not an expert in writing UDFs and have started just a few months back. From what I understand, I can get the index of the interfacial cells using F_C0 and F_C1 and update these using DEFINE_ADJUST. <\/p>\n<p>Can someone please give some hints on the correct way of doing this? Any help is much appreciated. Thanks in advance.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/031\/42NV7YLFVAWV.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/031\/42NV7YLFVAWV.png\" alt=\"keyhole2.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-162572","topic","type-topic","status-closed","hentry","topic-tag-interfacial-cells-1","topic-tag-laser-heating-1","topic-tag-solidification-melting-1","topic-tag-vof"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_view_count":["296"],"_bbp_likes_count":["0","0"],"_bbp_forum_subforum_count":["0"],"_btv_view_count":["857"],"_bbp_subscription":["242319"],"_bbpmt_movedon":["2022-08-26 07:19:04"],"_bbpmt_movedfrom":["27819"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["162572"],"_bbp_forum_id":["27792"],"_bbp_engagement":["25","5120","167859","262268"],"_bbp_voice_count":["4"],"_bbp_reply_count":["9"],"_bbp_last_reply_id":["193186"],"_bbp_last_active_id":["193186"],"_bbp_last_active_time":["2021-12-20 17:34:07"]},"test":"pawan"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/162572","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\/162572\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=162572"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
