Dear community,<\/p>\n

I would like to simulate a magnetic field behavior around a copper tape, including the inside the tape itself:
Radius of the tape is 18.5mm
thickness 0.1mm
height 4mm
One face of the tape is connected to GND on the other I apply a current of 100 A. Here you can found the setup for better understanding. The air enclosure is not included here:
\"\"<\/p>\n

Problem appears, when I solve the problem the magnetic field inside the tape is always very small:
\"\"<\/p>\n

 <\/p>\n

  1. question<\/strong>: What I am doing wrong? Should I increase the number of mesh divisions inside the tape?<\/li>\n
  2. question<\/strong>: I tried to increase sweep number of divisions inside the tape but I cannot go above 15 divisions, above that I get the following errrors:
    Error: An error occured during sweeping meshing a face. Changing element sizing parameters might help.
    Warning: Quad map meshing failed on one or more surfaces. A surface could be narrow with many boundary edges which may not have been properly paired up for meshing.  Using hard size controls on the boundary edges to force the same number of divisions might help.
    <\/em>Error: A mesh could not be generated using the current meshing options and settings.
    <\/em><\/span>How can I increase the layer number beyond 15?\n

    I know there is an option to use shell elements, but lets say Iam interesting what happening inside the tape, so I would like ot avoid using that.
    I also inlcude the whole project as .wbpz here: https:\/\/drive.google.com\/file\/d\/1-M8f1fBen5A95V3_FEKasRTQ3m5TKxKt\/view?usp=sharing<\/p>\n

    Thank you for the asnwers!<\/li>\n<\/ol>\n","protected":false},"template":"","class_list":["post-310241","topic","type-topic","status-closed","hentry","topic-tag-magneticfield-1","topic-tag-magnetostatic","topic-tag-solenoid-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["293669","50680","187258"],"_bbp_author_ip":["23.52.43.88"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["367"],"_edit_lock":["1696521391:231504"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["310241"],"_bbp_forum_id":["27791"],"_bbp_engagement":["50680","187258","293669"],"_bbp_voice_count":["3"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["310465"],"_bbp_last_active_id":["310465"],"_bbp_last_active_time":["2023-10-06 20:53:52"]},"test":"norbert-galcern-ch"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/310241","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\/310241\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=310241"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
