Static simulation with only bolt preload on the structure<\/p>\n<p>2 I add a torque load on the structure.<\/p>\n<p>3 Solution combination between this two steps, I subtract the results of the first step from the results of the second step <\/p>\n<p>Now i want to use the fatigue tool and assign a constant amplitude load for the solution combination and a constant load for the bolt pretension, or, at least, only the constant ampitude load for the solution combination to evaluate the demage on my tructure.<\/p>\n<p>Is this a good approach?<\/p>\n<p>I want to use the same method using Ncode design life, but I have a problem, when connecting &quot;static structural&quot; with &quot;ncode&quot; the combined results obtained with solution combination are not passed to ncode.<\/p>\n<p>How can I import the combination in Ncode?<\/p>\n<p>Thanks very much for any help.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/257\/F1PE2EF1QQQ8.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/257\/F1PE2EF1QQQ8.png\" alt=\"Cattura.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-160244","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_view_count":["236"],"_bbp_likes_count":["0","0"],"_bbp_forum_subforum_count":["0"],"_btv_view_count":["2305"],"_bbp_subscription":["254317","294122"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["160244"],"_bbp_forum_id":["27791"],"_bbp_engagement":["69","490","210405","294122"],"_bbp_voice_count":["4"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["308209"],"_bbp_last_active_id":["308209"],"_bbp_last_active_time":["2023-09-23 17:07:44"]},"test":"knculodamato95gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/160244","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\/160244\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=160244"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
