There is an inert gas atmosphere above the solid matrix. Now, the laser energy is a Gaussian energy surface heat source, which I have converted to a volumetric heat source.The following problems occur during laser action:<\/p>\n<p>1.The density, thermal conductivity and specific heat capacity parameters of the set material are set to fixed values (divided into two types: before and after the melting temperature, and the paste zone is a piecewise-linear curve), and the melting point is set to 1690K, but why does the velocity vector appear at 1580K? As shown in the figure below, the volume fraction equivalent surface of the solid phase is selected as 0.5.<\/p>\n<p>Any help is much appreciated.Thank you very much!<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/18-08-2023-1692341381-one.PNG\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/18-08-2023-1692341463-two.PNG\" alt=\"\"><\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/18-08-2023-1692341482-three.PNG\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/18-08-2023-1692341494-four.PNG\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/18-08-2023-1692341504-five.PNG\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-302032","topic","type-topic","status-closed","hentry","topic-tag-interface","topic-tag-melting-solidification-2","topic-tag-SelectiveLaserMelting-1","topic-tag-vof-model"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["5587","199"],"_bbp_author_ip":["104.102.248.140"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["344"],"_bbp_likes_count":["1"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["302032"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","5587"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["302657"],"_bbp_last_active_id":["302657"],"_bbp_last_active_time":["2023-08-22 07:50:47"]},"test":"shiyan9537outlook-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/302032","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\/302032\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=302032"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
