I started experimenting in static structural to see if this would work (picture attached), and it did. Then I moved to a simplified version of my scenario in explicit dynamics using beams instead of bones (picture attached), and this worked as well. But when I used two bones in explicit dynamics, made the bonded contact, and applied the force, the sim went crazy (picture attached). Does anyone know why this might be happening, and how I can recreate my results from static structural in explicit dynamics? Something to note is that I got the message &#8220;time step too small&#8221; when I ran that third simulation<\/p>\n<p><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/07\/21-07-2022-1658432324-Static structural bones.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/07\/21-07-2022-1658432324-Static structural bones.jpg\" alt=\"\" width=\"1428\" height=\"777\"><\/a><\/p>\n<p>&nbsp;<\/p>\n<p><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/07\/21-07-2022-1658432294-Exp Dyn Beams.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/07\/21-07-2022-1658432294-Exp Dyn Beams.jpg\" alt=\"\" width=\"1387\" height=\"595\"><\/a><\/p>\n<p>&nbsp;<\/p>\n<p><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/07\/21-07-2022-1658433222-Exp Dyn Bones.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/07\/21-07-2022-1658433222-Exp Dyn Bones.jpg\" alt=\"\" width=\"1344\" height=\"702\"><\/a><\/p>\n","protected":false},"template":"","class_list":["post-219389","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["259986","83"],"_bbp_author_ip":["204.2.243.141"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["884"],"_bbp_status":["publish"],"_edit_lock":["1658433281:186947"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["219389"],"_bbp_forum_id":["27814"],"_bbp_engagement":["83","259986"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["219584"],"_bbp_last_active_id":["219584"],"_bbp_last_active_time":["2022-07-22 18:29:33"]},"test":"greena18mcmaster-ca"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/219389","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\/219389\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=219389"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
