The thermal calculation worked well, but I have problems with the subsequent static calculation.&nbsp;I hope that you can help me.<\/p>\n<p>It is a simple flange, which is available as a half model. A tie rod is welded to this flange. The aim of the static calculation is to calculate the distortion and the residual stress from the thermal load.<\/p>\n<p>I have tried different constraints, but the calculation stops after a short time and the results up to that point are very strange.&nbsp;<\/p>\n<p>Here is a picture with the result of the thermal calculation. First I defined a fixed support at the outer holes. Then I defined an external displacement without a degree of freedom on the symmetry plane and that the weld seams must not move in the z-direction (I had once seen this in an example).&nbsp;<\/p>\n<p>The result is always approximately the same. The first weld (there are a total of two on each side) stretches\/displaces to such an extent that convergence is no longer achieved.<\/p>\n<p>Can anyone help me with how to set the support? Enclosed are the pictures and the error message.<\/p>\n<p>Many thanks in advance.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/07\/04-07-2024-1720094415-thermal-result.png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/07\/04-07-2024-1720094426-mechanical-result.png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/07\/04-07-2024-1720094440-mechanical-result_2.png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/07\/04-07-2024-1720094450-errors.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-370475","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["157"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["88"],"_bbp_notification_enabled":["73007","73007","73007","73007"],"_bbp_topic_id":["370475"],"_bbp_forum_id":["27791"],"_bbp_engagement":["88","50557"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["371258"],"_bbp_last_active_id":["371258"],"_bbp_last_active_time":["2024-07-10 07:15:14"]},"test":"38c38684d534cf5bfa75edcd76582c6f1c624a53"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/370475","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\/370475\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=370475"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
