Unfortunately, no matter how fine the mesh in the simulation it doesn&#8217;t match the analytic solution. I also checked the material properties in my simulation (resistance and magnetic permeability), but those seem to be correct. I used a cylindrical 50mm long wire with a radius of 1,3mm. Therefore I could use the Biot-Savart law for straight, finite wires for my analytic approach.<\/p>\n<p><\/p>\n<p>I used the magnetostatic tool in Ansys Workbench. I know that my simulation uses Solid117 elements for the calculation, but I couldn&#8217;t find out how magnetic fields created by such elements are calculated. Pictures of the equation I used and the comparison of both magnetic fields are attached. Maybe someone has an idea and can help me out with that problem.<\/p>\n<p><\/p>\n<p>Best regards<\/p>\n<p><\/p>\n<p>Sebastian<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-33669","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["5841"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["1707"],"_bbp_subscription":["239187"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["33669"],"_bbp_forum_id":["27793"],"_bbp_engagement":["163133","163166"],"_bbp_voice_count":["2"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["80371"],"_bbp_last_active_id":["80371"],"_bbp_last_active_time":["2019-03-14 11:08:31"]},"test":"sebastian93"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/33669","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\/33669\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=33669"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
