Unfortunately, I could not find any information on this topic in the documentation available at:&lt;\/p&gt;&lt;p data-start=&#8221;313&#8243; data-end=&#8221;462&#8243;&gt;<a href=\"https:\/\/ansyshelp.ansys.com\/public\/account\/secured?returnurl=\/Views\/Secured\/MotorCAD\/v252\/en\/Motor-CAD_UG\/MotorCAD\/topics\/cuboidal_winding_model.html\" target=\"_new\" rel=\"noopener\">https:\/\/ansyshelp.ansys.com\/public\/account\/secured?returnurl=\/Views\/Secured\/MotorCAD\/v252\/en\/Motor-CAD_UG\/MotorCAD\/topics\/cuboidal_winding_model.html<\/a>&lt;\/p&gt;&lt;p data-start=&#8221;464&#8243; data-end=&#8221;640&#8243;&gt;I am particularly interested in how the k-values are calculated in the three spatial directions. Could you please provide the corresponding calculation formulas or methodology?&lt;\/p&gt;&lt;p data-start=&#8221;642&#8243; data-end=&#8221;962&#8243;&gt;I have also noticed that changing the thermal conductivity or the impregnation quality does not affect the k-values of the stator winding. This appears to contradict the explanation provided in the documentation linked above. The same behavior can be observed for the rotor winding of a salient-pole synchronous machine.&lt;\/p&gt;&lt;p data-start=&#8221;964&#8243; data-end=&#8221;1051&#8243;&gt;I would appreciate your clarification on this matter and look forward to your response.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-460254","topic","type-topic","status-publish","hentry","topic-tag-ansys-thermal-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27793"],"_bbp_topic_id":["460254"],"_bbp_author_ip":["130.75.213.19"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["460254"],"_bbp_last_active_time":["2026-06-23 11:25:50"],"_bbp_reply_count":["0"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["1"],"_bbp_engagement":["701942"],"_btv_view_count":["37"],"_bbp_topic_status":["unanswered"]},"test":"mohamad-shheibarial-uni-hannover-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/460254","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\/460254\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=460254"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
