I tried using periodic boundary conditions using the concept of remote points and constraint equations, but I&#8217;m not sure how correct are those. The results are not making any sense and I&#8217;m also getting a warning message regarding the boundary conditions. I also used displacement rather than remote displacement. The simulation was looking good but it gave me around 2000 MPa stress with just an applied displacement of 0.2mm (the material used was Aluminum alloy from ANSYS Engineering Data). Can someone please help me understand the exact\/actual boundary conditions which I should implement so that I can complete my analysis soon?&nbsp;<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/03cea4f8-780e-4d85-a0ee-ab9500a8040f\/25109f78-c797-441a-83f3-ab9500adfe87_boundary-conditions.jpg?width=690&amp;upscale=false\" alt=\"Applied boundary conditions with remote displacement\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/03cea4f8-780e-4d85-a0ee-ab9500a8040f\/e3dc8502-fe3a-43d8-9aaf-ab9500ae3a2c_constraint-equation1.jpg?width=690&amp;upscale=false\" alt=\"Constraint equation\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/03cea4f8-780e-4d85-a0ee-ab9500a8040f\/66736b88-3239-4b08-8be7-ab9500ae5198_constraint-equation2.jpg?width=690&amp;upscale=false\" alt=\"Constraint equation 2\"><\/p>\n<p><\/p>\n<p>Thank you<\/p>\n<p><\/p>\n<p>Varun<\/p>\n","protected":false},"template":"","class_list":["post-42480","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["14660"],"_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"],"_btv_view_count":["759"],"_bbp_subscription":["249515"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["42480"],"_bbp_forum_id":["27791"],"_bbp_engagement":["79","175340"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["110376"],"_bbp_last_active_id":["110376"],"_bbp_last_active_time":["2020-04-06 20:26:16"]},"test":"vagraw13"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/42480","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\/42480\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=42480"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
