I am trying to do a frequency sweep simulation for a long, rectangular 3D, strip of metal. I am looking to extract the measured inductance and Q factor (losses) across the metal strip.<\/p>\n

I want to use two terminals for this and make it so that these terminals\/ports\/references do not add inductance<\/strong>. I have attached a picture of my layer stack.<\/div>\n
\"\"<\/a><\/div>\n

1. I have tried to make terminals out of the two smallest, opposite faces of the yellow inductor by selecting the two faces, making each of them an object from the face, making each of the objects a terminal lumped port, and then assigning each of the lumped ports a terminal. I also made the top face of the pink material a pec ground reference. However, that did not work and the error said that there were too few conductors found on the port(s).<\/div>\n
 <\/div>\n
2.  I also tried to make a ground reference loop. I’ve attached a top-down view of the layers. The green square frame\/loop is the ground reference conductor (a pec). I then drew two rectangles connecting the top edges of the inductor ends to the green frame. I made these two rectangles into ports, and making them lumped terminal ports automatically assigned terminals to them. This works and simulates, but I notice that the green frame adds extra inductance.<\/div>\n
\"\"<\/a><\/div>\n
 <\/div>\n
What is the way to simulate this without any added inductance in driven terminal mode?<\/div>\n

Thanks in advance!<\/div>\n","protected":false},"template":"","class_list":["post-361587","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["81183","28551","16925"],"_bbp_author_ip":["23.52.43.88"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["639"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1712928966:295341"],"_bbp_topic_id":["361587"],"_bbp_forum_id":["27793"],"_bbp_engagement":["16925","28551","81183"],"_bbp_voice_count":["3"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["362257"],"_bbp_last_active_id":["362257"],"_bbp_last_active_time":["2024-04-15 13:55:29"]},"test":"abatrachandrew-cmu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/361587","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":2,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/361587\/revisions"}],"predecessor-version":[{"id":361780,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/361587\/revisions\/361780"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=361587"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
