So I have two cases: one where I simulate impacts and the second one where I apply the force reaction from the contact region in case 1 to the same model as input (Instead of simulating the impact) but the results don&#8217;t match. I show where I apply the force and the girder displacements. The one with the larger magnitude is the case of simulating the collision. Any suggestions on how to make them match.&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/27-02-2024-1709038419-mceclip9.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/27-02-2024-1709038288-mceclip8.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/27-02-2024-1709037929-mceclip4.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/27-02-2024-1709038058-mceclip5.png\"><\/p>\n","protected":false},"template":"","class_list":["post-354606","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["78929","20905","83"],"_bbp_author_ip":["23.206.193.154"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["379"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["354606"],"_bbp_forum_id":["27791"],"_bbp_engagement":["83","20905","78929"],"_bbp_voice_count":["3"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["354888"],"_bbp_last_active_id":["354888"],"_bbp_last_active_time":["2024-03-01 18:57:55"]},"test":"oglawal2illinois-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/354606","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\/354606\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=354606"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
