When I run this model, it can be sloved but the answer in two cyclic boundary regions are not matched with wach other, and there is a warning which writes [No Cyclic constraint equations are not created for Thermal DOF&#8217;s(Temp)].&lt;\/p&gt;&lt;p&gt;I wonderd how can I calculate Thermal with Cyclic models correctly ( which means the cyclic regions are matched with each other ) , or it&#8217;s not availble from the point of software functions? I found the explanation about Thermal constraint in Ansys website which said that [Cyclic symmetry solution does not work for elements that have thermal and hydrostatic pressure degrees of freedom.], you can see that on the pic and the link. <a href=\"https:\/\/ansyshelp.ansys.com\/public\/account\/secured?returnurl=\/Views\/Secured\/corp\/v251\/en\/ans_cycsym\/advcyclmnt.html\">https:\/\/ansyshelp.ansys.com\/public\/account\/secured?returnurl=\/Views\/Secured\/corp\/v251\/en\/ans_cycsym\/advcyclmnt.html<\/a><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/04\/14-04-2025-1744609053-pics.png\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-428777","topic","type-topic","status-answered","hentry","topic-tag-Analysisstatic-thermal-static-1","topic-tag-constraints"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["291846"],"_bbp_topic_id":["428777"],"_bbp_subscription":["294449","8101"],"_bbp_author_ip":["2408:8936:1010:67e8:bd5c:78d8:1948:b1cb"],"_bbp_last_reply_id":["429475"],"_bbp_last_active_id":["429475"],"_bbp_last_active_time":["2025-04-21 02:12:42"],"_bbp_reply_count":["4"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["294449","8101"],"_btv_view_count":["279"],"_bbp_topic_status":["answered"]},"test":"loiteringfishgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/428777","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/428777\/revisions"}],"predecessor-version":[{"id":429075,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/428777\/revisions\/429075"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=428777"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
