The simulation basically consists of two flat parallel plates of size ~100 cm x 28 cm x 1.27 cm with a fixed voltage and I&#8217;m trying to measure the E-field between them. The difficulty comes when I put in a small cube with a voltage on one of the field plates to simulate the effect of an imperfection on them:<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/c0dcbc44-6c95-4edb-a25e-aa630184be0a\/96a0bc06-99b7-4924-8239-abce011aae78_capture.jpg?width=690&amp;upscale=false\" alt=\"Two parallel field plates with small cube of charge\"><\/p>\n<p><\/p>\n<p>(You can see the small cube on the bottom field plate that I put in.)<\/p>\n<p><\/p>\n<p>If I make the cube smaller than about 1 mm, I cannot plot the mesh on the small charge (even though I can solve). It simply says,<strong> &#8220;Plot &#8216;ChargeMesh&#8217; becomes invalid due to no available mesh.&#8221;<\/strong> This&nbsp;message persists even when I&nbsp;apply a special Mesh Operation on the cube such that the length of the mesh is smaller than the size of the cube. Note that I&#8217;ve also set the Model Resolution (in Initial Mesh Settings) to Auto. Thus,&nbsp;even though I&#8217;m seeing some sort of effect in the E-field from the cube, there is no clear way for me to check if Maxwell is really properly meshing and taking the cube&nbsp;into account when solving.<\/p>\n","protected":false},"template":"","class_list":["post-44683","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["16864"],"_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":["1139"],"_bbp_subscription":["240504"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["44683"],"_bbp_forum_id":["27793"],"_bbp_engagement":["23","165821"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["118302"],"_bbp_last_active_id":["118302"],"_bbp_last_active_time":["2020-06-19 13:02:30"]},"test":"gordon"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/44683","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\/44683\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=44683"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
