These vacuum chambers are located in an area where a low frequency oscillating field from a coil is applied (f ~ 3 Hz &#8211; 5000 Hz).<br \/>The goal of the simulation is to find the eddy currents distribution in the chamber walls along with the transmitted magnetic field inside the tower as a function of the applied field frequency as well as a function of the permeability and conductivity of the chamber material.<br \/>The difficulty is to mesh such a system. In Comsol there is a way to avoid 3D meshing of the chamber walls thickness by replacing them by an average surface to which a special &#8220;transition boundary condition&#8221; is applied. Is this feasible in Maxwell 3D?<\/p>\n<p>Thanks a lot for any help\/hints.<\/p>\n","protected":false},"template":"","class_list":["post-374204","topic","type-topic","status-closed","hentry","topic-tag-quasi-static-1","topic-tag-maxwell"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["435556","186775"],"_bbp_author_ip":["192.93.53.6"]," _bbp_last_reply_id":["0"],"_btv_view_count":["175"]," _bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["374204"],"_bbp_forum_id":["27793"],"_bbp_engagement":["186775","435556"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["375771"],"_bbp_last_active_id":["375771"],"_bbp_last_active_time":["2024-08-02 18:31:50"]},"test":"75bd85c5f88e2de9d14c805f6408f0533119ca05"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/374204","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\/374204\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=374204"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
