I would like to ask for some assistance from the community.&lt;br&gt;&lt;br&gt;This is probably a basic question, so I apologize beforehand. I need to plot the flux density as a function in time in a specific cross sectional area in a transformer (a part of the ferromagnetic core), I managed to add the polyline and see how mag B changes as a function of distance, but I&#8217;m not sure which is the best path to get B(t) is. I understand that flux distribuition is not homogenous in a given area, so distance is still very relevant. Is doing the average magnitude of B the right choice here, and what is the best way to do this and get a resulting plot? I&#8217;m aware that the FluxLinkage measurement of the windings exist, and that can they can be used to calculate B if the amount of turns and area is known, but I&#8217;m uncertain if this adequately captures the flux density in the core. Also, there is more than 1 winding around the core area (may be additive or subtractive in terms of flux), so I&#8217;m not sure what each FluxLinkage is actually representing, thats why I wanted a solution like the one using Polyline, unless there is very clear explanation regarding this measurement. In any case, if information on both methods could be given, I would appreciate it very much. That is because I also need to know B in sections of the transformer that doesn&#8217;t contain windings, so something like the polyline would be needed (the core design is very different and complex). &lt;br&gt;&lt;br&gt;Thank you very much for your time and any assistance you can provide. If I&#8217;m not asking too much, can you give a step by step procedure to achieve this, please. &lt;\/p&gt;&lt;\/p&gt;&lt;\/p&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-457981","topic","type-topic","status-publish","hentry","topic-tag-ansys-maxwell-2d","topic-tag-magnetic-transient-solver-2","topic-tag-transformer"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27793"],"_bbp_topic_id":["457981"],"_bbp_subscription":["680555","675360"],"_bbp_author_ip":["179.160.36.152"],"_bbp_last_reply_id":["458117"],"_bbp_last_active_id":["458117"],"_bbp_last_active_time":["2026-05-13 21:33:33"],"_bbp_reply_count":["2"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["680555","675360"],"_btv_view_count":["65"],"_bbp_topic_status":["unanswered"],"_edit_last":["680555"],"_bbp_revision_log":["a:3:{i:457984;a:2:{s:6:\"author\";i:680555;s:6:\"reason\";s:0:\"\";}i:457985;a:2:{s:6:\"author\";i:680555;s:6:\"reason\";s:0:\"\";}i:457986;a:2:{s:6:\"author\";i:680555;s:6:\"reason\";s:0:\"\";}}"],"_edit_lock":["1778586561:680555"]},"test":"pepecarte22gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/457981","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":3,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/457981\/revisions"}],"predecessor-version":[{"id":457986,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/457981\/revisions\/457986"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=457981"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
