For simulation I am using ANSYS 2021 R1 and for providing laser beam I am using commands from APDL console (image below).&nbsp; When I simulate processes and ANSYS solve it, there are temperatures above melting temperature (which is correct and fine) and also temperatures above vapouring temperature of the material (which is not correct). I am looking for a solution how &nbsp;to turn off\/kill nodes, which reaches temperatures above 2500 &deg;C.&nbsp; This solution should solve problem to create keyhole welding. There are a few major problems. Since I am doing it in one continuous step &#8211; I cannot do it&nbsp; by elements birth and death provided by ANSYS&nbsp; &#8211; because it would turn it on\/off for whole step. So It had to be performed simultaneously by movement of the laser beam. Every help would be appreciated.<\/div>\n<div>&nbsp;<\/div>\n<div>Thanks in advance!<\/div>\n<div>&nbsp;<\/div>\n<div>Martin Hnilica<\/div>\n<div><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/12\/07-12-2022-1670396070-mceclip1.png\"><\/div>\n","protected":false},"template":"","class_list":["post-243190","topic","type-topic","status-closed","hentry","topic-tag-3DTransientThermal-1","topic-tag-ansys-apdl","topic-tag-ekill-elements"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["269940","50680","282032"],"_bbp_author_ip":["23.192.164.14"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["2407"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["243190"],"_bbp_forum_id":["27791"],"_bbp_engagement":["50680","269940","282032"],"_bbp_voice_count":["3"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["282434"],"_bbp_last_active_id":["282434"],"_bbp_last_active_time":["2023-05-04 19:19:11"]},"test":"martin-hnilicastuba-sk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/243190","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\/243190\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=243190"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
