I am using Ansys Mechanical primarily to investigate thermal stress and strain between plates of diferent material soldered together. I built a solidworks assmebly of 4 rectangular prisms mated together forming a stack and imported the STEP file to WB and then Mechanical. Each body has been assigned a different material with differing CTEs. Under my Static Structural (B5) I set an Environmental Temperature of 22C and inserted a Thermal Condition that varies with my steps. When I go to solve I get a warning that the reference temperatures for some of my CTEs differ from that set by the environment. From looking at resources it seems that I need to change the Reference Temperature of each body from &#8220;By Environment&#8221; to &#8220;By Body&#8221;, however this box is greyed out and I am unable to do so. Any advice would be greatly appreciated.<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/07\/27-07-2023-1690468814-Ansys forum1.PNG\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-295172","topic","type-topic","status-closed","hentry","topic-tag-ansysworkbench-ansys-staticstructural","topic-tag-2022-r1-1","topic-tag-Analysisstatic-thermal-static-1","topic-tag-APDLthermal-1","topic-tag-mechanical-thermal-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["290301","13927"],"_bbp_author_ip":["23.206.193.154"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["3568"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["295172"],"_bbp_forum_id":["27791"],"_bbp_engagement":["13927","290301"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["295299"],"_bbp_last_active_id":["295299"],"_bbp_last_active_time":["2023-07-28 07:02:38"]},"test":"ashpwrx-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/295172","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\/295172\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=295172"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
