Can I please ask for help with electrostatic pull-in simulation for MEMS switch in the workbench? Because my structure has to use floating potential condition, Maxwell is the best option for me so far. Please let me know if I can apply this boundary condition in APDL <span class=\"safeEmoji nativeEmoji\">?<\/span> (I have read both &quot;<em>Coupled-field analysis guide&quot;<\/em> and &quot;<em>MEMS Multiphysics simulation in Ansys workbench<\/em> &quot; tutorial, but nothing about floating potential condition there). <\/p>\n<p>I can get deflection results from my simulation by using Maxwell and static structural analysis systems. However, my structure cannot simulate pull-in\/collapse states. I have been told to use a two-way interaction method, like FSI (fluid structure interaction) tutorial, to transfer data between Maxwell and Transient structural in order to have &quot;snaps down&quot; mode. However, there is a Maxwell system coupling issue since my solution type for Maxwell is electrostatic. I believe that system coupling has limited support for Maxwell as shown in the following picture (not able to connect system coupling setup cell to Maxwell). <\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/123\/BQNZC5M3CP3N.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/123\/BQNZC5M3CP3N.png\" alt=\"Picture1.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-159110","topic","type-topic","status-closed","hentry","topic-tag-coupled-simulation","topic-tag-electrostatics","topic-tag-maxwell","topic-tag-mems","topic-tag-system-coupling"],"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":["1896"],"_bbp_likes_count":["0"],"_bbp_subscription":["239258"],"_bbpmt_movedon":["2022-07-01 17:13:09"],"_bbpmt_movedfrom":["151970"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["159110"],"_bbp_forum_id":["27793"],"_bbp_engagement":["25","200131"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["180791"],"_bbp_last_active_id":["180791"],"_bbp_last_active_time":["2021-06-17 18:11:07"]},"test":"22081452student-uwa-edu-au"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/159110","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\/159110\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=159110"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
