I want to ensure that the right side of the breast, represented by the red line, can only move in the positive x-axis direction during compression while being free to move in the y and z directions. Similarly, the left side of the breast, represented by the red line, can only move in the negative x-axis direction while being free to move in the y and z directions. I plan to perform this simulation in Ansys Mechanical.I would like to ask is there a way to set my above boundary conditions?<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/03-08-2023-1691051394-9.png\" alt=\"\"><\/p>\n<p>I had already try symmetry and asymmetry in the contact.&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-296261","topic","type-topic","status-closed","hentry","topic-tag-boundary-conditions"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["285206","32680"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1788"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["296261"],"_bbp_forum_id":["27791"],"_bbp_engagement":["32680","285206"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["298147"],"_bbp_last_active_id":["298147"],"_bbp_last_active_time":["2023-08-04 10:07:39"]},"test":"jiaweiii0610gapp-nthu-edu-tw"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/296261","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\/296261\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=296261"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
