(TOP IMAGE)<\/p>\n<p>2) core loss &#8211; this method is definitely proportional to f^2, but removing the eddy effects as suggested when activating core losses means that I no longer see the expected distribution of core losses. (BOTTOM IMAGE)<\/p>\n<p><\/p>\n<\/p>\n<p>I guess my question is, how are the losses being calculated under eddy effects if they&#039;re not dependent on frequency? How can I get an accurately frequency-dependent loss calculation that also still incorporates eddy effects to get the expected distribution pattern?<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/164\/PM4B226LZ7FN.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/164\/PM4B226LZ7FN.png\" alt=\"Screen Shot 2021-07-13 at 10.04.46 AM.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-160344","topic","type-topic","status-closed","hentry","topic-tag-core-loss","topic-tag-eddy-current-solver","topic-tag-induction-1","topic-tag-induction-coil","topic-tag-maxwell"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["4189"],"_bbp_likes_count":["0"],"_bbp_subscription":["252280","294794"],"_bbpmt_movedon":["2022-07-01 17:07:26"],"_bbpmt_movedfrom":["151970"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["160344"],"_bbp_forum_id":["27793"],"_bbp_engagement":["94","178124","178144","186775","294794"],"_bbp_voice_count":["5"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["310065"],"_bbp_last_active_id":["310065"],"_bbp_last_active_time":["2023-10-04 14:18:29"]},"test":"tpaplham"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/160344","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\/160344\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=160344"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
