I have a model consisting of several parts held together by bolts. Firctional contact is applied between the bodies. The bolts will be pre tensionsed in 3 stages. Due to this configuration the model is not very stable and I have issues getting it to converge. nWhat i would like to do is to add a zero displacement to some of the parts i the first 2 load steps, so that the bolt pre tensioning steps will converge. Thereafter I would like to disable the displacement before i apply the external loads. Is this possible?nYour help i appreciated. n<\/p>\n","protected":false},"template":"","class_list":["post-50258","topic","type-topic","status-closed","hentry","topic-tag-ansys-mechanical","topic-tag-bolt-pretension","topic-tag-constraints","topic-tag-loadsteps"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["22502"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["?4fX"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["2706"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["50258"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","183759"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["134906"],"_bbp_last_active_id":["134906"],"_bbp_last_active_time":["2020-12-03 13:57:28"]},"test":"ladderdale"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/50258","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\/50258\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=50258"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
