There&#039;re no inertial loads that&#039;s why I don&#039;t care about material and chose it to be default structural steel. The only one boundary condition is a Force applied to the second beam (which is not connected to the ground). I want to investigate the behaviour of such beam system under different values of that Force. <\/p>\n<p>The problem is that when I don&#039;t turn on Quasi-Static option in Solver Controls, this model converges only when the force is &lt; 145 N. But if I turn on Quasi-Static solution it converges in wider range of force value but it converges to another solution which is not identical to the original one. <\/p>\n<p>So the question primarily is this: why Quasi-Static converges better than usual Static and why it gives another results, while I don&#039;t have any inertial loads?<\/p>\n","protected":false},"template":"","class_list":["post-169047","topic","type-topic","status-closed","hentry","topic-tag-beamsystem-1","topic-tag-Quasistatic-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["4227"],"_bbp_likes_count":["0"],"_bbp_subscription":["250993"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["169047"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","250993"],"_bbp_voice_count":["2"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["213559"],"_bbp_last_active_id":["213559"],"_bbp_last_active_time":["2022-05-04 04:58:06"]},"test":"alpatovivanviktorovichgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/169047","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\/169047\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=169047"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
