Basically I am performing a transient thermal analysis followed by a transient structural analysis. <\/p>\n<p>First of all I am importing a surface map of temperatures to a body, applying some boundary conditions in terms of insulation and convection and I am investigating 1) the temperature in the center of the body and 2) the time evolution of the temperature in the whole body.<\/p>\n<p>After that I am importing this temperature time evolution into the transient mechanical analysis. So far so good. The problem is that when I perform the simulation, the temperature is applied to the body at time 0 and the body deforms (expands) under this thermal load (picture 1). In my specific case however, the geometry I am importing is the already heated\/deformed geometry and what I want to investigate is the contraction of the geometry as it cools down following the cooling process simulated in the first part.<\/p>\n<p>Any idea if and how this could be implemented?<\/p>\n<p>Thank you,<\/p>\n<p>Aron<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/398\/NQUTWQXHCYHO.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/398\/NQUTWQXHCYHO.png\" alt=\"picture1.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-163232","topic","type-topic","status-closed","hentry","topic-tag-ansys-mechanical","topic-tag-ansys-student","topic-tag-ansys-workbench","topic-tag-transient-structural","topic-tag-transient-thermal"],"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":["3426"],"_bbp_likes_count":["0"],"_bbp_subscription":["235510"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["163232"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","235510"],"_bbp_voice_count":["2"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["195276"],"_bbp_last_active_id":["195276"],"_bbp_last_active_time":["2021-10-22 22:48:39"]},"test":"colussoastudent-ethz-ch"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/163232","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\/163232\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=163232"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
