I have created an enclosure using spaceclaim&#039;s &quot;enclosure&quot; function, then tried to mesh this using mechanical (transient thermal). I&#039;ve defined material properties of the enclosure and the body in question (density, thermal conductivity and specific heat capacity), and have applied a temperature of 35 at the top face of the enclosure with perfect insulation at the surface level. When I run the transient analysis with a uniform initial temperature of 22c, I get a uniform temperature of 35 across the body and enclosure after the first timestep (0.001s). I wanted to ask what I&#039;m doing incorrectly, am I missing a property to be applied such as heat flux etc or are my material properties wrong? <\/p>\n<p><\/p>\n<\/p>\n<p>Photos of my setup can be seen below and any assistance would be appreciated.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/739\/SX4SMLMYMI28.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/739\/SX4SMLMYMI28.png\" alt=\"1 (1).PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-160933","topic","type-topic","status-closed","hentry","topic-tag-ansys-mechanical","topic-tag-ansys-workbench","topic-tag-apdl","topic-tag-spaceclaim","topic-tag-transient-analysis"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["1658"],"_bbp_likes_count":["0"],"_bbp_subscription":["255218"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["160933"],"_bbp_forum_id":["27791"],"_bbp_engagement":["88","210874"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["187470"],"_bbp_last_active_id":["187470"],"_bbp_last_active_time":["2021-08-04 13:43:00"]},"test":"daniyalsid26gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/160933","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\/160933\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=160933"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
