If I can use that option, which of the 2 surface do I turn into a conducting plate? Just one? Both?&lt;\/p&gt;&lt;p&gt;Another method I am wondering is do I make a copy of one of the bodies -&gt; extract just the face from the body (Create object from face) -&gt; Simplify face into a sheet -&gt; Assign thermal -&gt; Conducting plate. If I can do this method, do I leave the other 2 bodies untouched? Then it&#8217;s essentially a conducting place as a sheet sandwiched between Object A and Object B&lt;br&gt;&lt;br&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/12\/03-12-2024-1733260410-Screenshot 2024-12-03 161317.png\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-396167","topic","type-topic","status-publish","hentry","topic-tag-aedt","topic-tag-AEDTICEPAK-1","topic-tag-thermal-resistance-1","topic-tag-thermal-simulation"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27793"],"_bbp_topic_id":["396167"],"_bbp_subscription":["473488","92143"],"_bbp_author_ip":["12.216.216.6"],"_bbp_reply_count":["2"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["473488","92143"],"_btv_view_count":["767"],"_bbp_topic_status":["unanswered"],"_bbp_last_reply_id":["439021"],"_bbp_last_active_id":["439021"],"_bbp_last_active_time":["2025-08-11 21:03:30"]},"test":"greg-harringtondrs-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/396167","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\/396167\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=396167"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
