I don&#8217;t know if default ANSYS bonded contact is the right setting for the analysis or maybe another one like frictionless (between phalanges and pins), frictional, etc.?. Maybe I&nbsp;have to add some joints into model?<\/p>\n<p><\/p>\n<p style=\"box-sizing: border-box; margin: 0px 0px 10px; font-size: 15px; overflow-x: hidden; font-family: 'Open Sans', Arial, Helvetica, sans-serif;\"><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/74929fcd-b55f-4508-b098-a9ad00d72557\/a0e1d8e8-ccd2-4141-9105-a9ae00182d2d_ansys.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p style=\"box-sizing: border-box; margin: 0px 0px 10px; font-size: 15px; overflow-x: hidden; font-family: 'Open Sans', Arial, Helvetica, sans-serif;\"><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/74929fcd-b55f-4508-b098-a9ad00d72557\/86beca78-0113-4e87-90b4-a9ae00185111_hand-orthosis.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p style=\"box-sizing: border-box; margin: 0px 0px 10px; font-size: 15px; overflow-x: hidden; font-family: 'Open Sans', Arial, Helvetica, sans-serif;\">&nbsp;<\/p>\n<p><\/p>\n<p style=\"box-sizing: border-box; margin: 0px 0px 10px; font-size: 15px; overflow-x: hidden; font-family: 'Open Sans', Arial, Helvetica, sans-serif;\">&nbsp;<\/p>\n<p><\/p>\n<p style=\"box-sizing: border-box; margin: 0px 0px 10px; font-size: 15px; overflow-x: hidden; font-family: 'Open Sans', Arial, Helvetica, sans-serif;\">Thank you for your help and support.<\/p>\n","protected":false},"template":"","class_list":["post-31968","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["4140"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["5294"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["31968"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","160648","160940"],"_bbp_voice_count":["3"],"_bbp_reply_count":["29"],"_bbp_last_reply_id":["79231"],"_bbp_last_active_id":["79231"],"_bbp_last_active_time":["2019-03-04 01:35:07"]},"test":"francisco-guerra"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/31968","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\/31968\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=31968"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
