To calculate inductance of a coil in the post-processing phase:   1) Go to &#8216;Maxwell 3D -> Results -> Solution Data&#8217;. On the convergence tab, note the &#8216;TotalEnergy (J)&#8217; of the last pass, and calculate the inductance with the formula L=4*TotalEnergy\/I_peak^2, where I_peak is the peak current of your coil  OR   2) In the Fields Calculator, integrate the &#8216;energy&#8217; over the volume &#8216;AllObjects&#8217; to get the &#8216;TotalEnergy&#8217;, and calculate the inductance with the abovementioned formula.  To calculate resistance of a coil in the post-processing phase:  In the Fields Calculator, integrate the &#8216;Ohmic-Loss&#8217; over the volume of your coil to get &#8216;P_ohmic&#8217;, and calculate the resistance with the formula R=2*P_ohmic\/I_peak^2  Details about the formulas can be found in Maxwell-help: Maxwell 2D Technical Notes -> Eddy Current Field Simulation -> Impedance Matrix -> Computing an Impedance Matrix -> Matrix Resistance\/Inductance.<\/p>\n","protected":false},"template":"","class_list":["post-164284","topic","type-topic","status-publish","hentry","topic-tag-electromagnetics-electronics","topic-tag-low-frequency-electromagnetics","topic-tag-maxwell","topic-tag-post-processing-maxwell"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["1-24-2023  20:20:09"],"_bbp_forum_id":["27819"],"_bbp_author_ip":["23.56.168.180"],"_btv_view_count":["10629"],"siebel_km_number":["2040140"],"product_version":[""],"km_published_date":["2015-08-31T12:57:27.000Z"],"family":["Electromagnetics & Electronics"],"application_name":["Maxwell"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/164284","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/164284\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=164284"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
