This plate will receive an impact of 5 m\/s from an external dropped object. Now I have not been able to get the solution to converge whenever I preload the bolts in transient. I created a static structural system where I was able to successfully preload the bolts. My question is there a way to take the pre-stressed model I have in static structural and use it in transient structural? This is for a non-linear analysis. Or is there a way where I can apply pre-load tension to the bolts and apply a 5 m\/s impact on to the plate all in transient structural? Because so far I have not been able to achieve convergence in transient structural with pre-loaded bolts. As you can see in the picture I am using beam connections as the bolts and the beams the plate is attached to are surface models. The plate itself is a 3D body. I have also attached a picture of my analysis settings for transient and the bolt pretension settings I currently have applied. Any help would greatly be appreciated.&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/23-02-2024-1708701906-mceclip0.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/23-02-2024-1708702043-mceclip1.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/23-02-2024-1708702075-mceclip2.png\"><\/p>\n","protected":false},"template":"","class_list":["post-353500","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["68891","240"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1595"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["353500"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","68891"],"_bbp_voice_count":["2"],"_bbp_reply_count":["24"],"_bbp_last_reply_id":["354404"],"_bbp_last_active_id":["354404"],"_bbp_last_active_time":["2024-02-28 19:08:56"]},"test":"salissa2slb-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/353500","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\/353500\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=353500"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
