The idea is to press a spherical tip onto a piece of bone by imposing a vertical remote displacement and recording the reaction forces induced. I first tried with only one step which worked and gave me the same reaction force than for the whole model. However, when I&#039;m increasing the number of steps (here I&#039;m trying 5), the model with the symmetry is not converging anymore (whereas the full model is converging). <\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/101\/H38F30I3AYQR.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/101\/H38F30I3AYQR.png\" alt=\"Simu.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-160965","topic","type-topic","status-closed","hentry","topic-tag-ansys-workbench","topic-tag-static-structural","topic-tag-symmetry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["929"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["160965"],"_bbp_forum_id":["27789"],"_bbp_engagement":["240","216222"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["187606"],"_bbp_last_active_id":["187606"],"_bbp_last_active_time":["2021-08-04 12:36:00"]},"test":"astrid-cantamessauliege-be"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/160965","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\/160965\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=160965"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
