The electric field plot without the added region looks good, whereas adding the region creates an unreasonable electric field. However, in the PowerPoint provided by Ansys, they successfully obtained the capacitance of two parallel plates without considering the surrounding region. I&#8217;ve also confirmed that including the region would alter the resulting value. Additionally, I can&#8217;t figure out why reducing the size of the region would increase the capacitance I simulated, assuming both regions are large enough.<\/p>\n","protected":false},"template":"","class_list":["post-296157","topic","type-topic","status-closed","hentry","topic-tag-AnsysMaxwellelectronics-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["290413","23217"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["542"],"_edit_lock":["1691068428:225769"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["296157"],"_bbp_forum_id":["27793"],"_bbp_engagement":["23217","290413"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["298513"],"_bbp_last_active_id":["298513"],"_bbp_last_active_time":["2023-08-07 12:27:14"]},"test":"lchiwei01gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/296157","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\/296157\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=296157"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
