I created a 15-turn coil using the &#8220;sweep along path&#8221; method (with a width of 0.15mm and a copper thickness of 0.035mm). I need to add an excitation current to it, but I have tried many methods and none of them worked. First, I tried &#8220;assign excitation -&gt; current&#8221;, but it failed. Then, I used &#8220;surface -&gt; section&#8221; to obtain a cross-section, and tried adding the excitation current through this cross-section, but it also failed. Finally, I chose the two end faces of the coil as &#8220;CoilTerminal&#8221;, then added the winding, but it also failed. The last method I tried was to use &#8220;bondwire&#8221; to connect the two ports, but it would intersect with other components (I am designing an FPCB that is close to the PI layer). So, how should I correctly add the excitation?If possible, I would appreciate it if you could provide me with the detailed steps. My AEDT version is 2024R2.Looking forward to your reply.<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/08-07-2026-1783530606-mceclip4.png\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/08-07-2026-1783530401-mceclip0.png\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/08-07-2026-1783530462-mceclip1.png\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/08-07-2026-1783530493-mceclip2.png\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/08-07-2026-1783530534-mceclip3.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-461075","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27793"],"_bbp_topic_id":["461075"],"_bbp_subscription":["707771"],"_bbp_author_ip":["13.213.47.232"],"_bbp_last_reply_id":["461223"],"_bbp_last_active_id":["461223"],"_bbp_last_active_time":["2026-07-12 07:23:21"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["1"],"_bbp_engagement":["707771"],"_btv_view_count":["36"],"_bbp_topic_status":["unanswered"]},"test":"1965064082qq-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/461075","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\/461075\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=461075"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
