There some issues are as follow:<\/div>\n<div class=\"gmail_default\">1. I finished all setup when I compared the force calculation between moving1.Torque and MST_Torque, before starting to analyse, it can setup Airgap_arc (Angle is 45deg) as an edge. However, the software said &#8220;TAU: Surface Mesh Generation Failed.&#8221; after I setup MST_Torque by fields calculator;<\/div>\n<div class=\"gmail_default\">2. It cannot setup Arigap_arc as edge of MST_Torque by fields calculator after finish all calculations because the button is disappear;<\/div>\n<div class=\"gmail_default\">3. The result of MST_Torque is wrong if the Airgap_arc cannot be setted as edge;<\/div>\n<div class=\"gmail_default\">4.There are some definitions that do not illustrate it, like SymmetryFactor. It cannot set the expressions in the field calculator if I don&#8217;t get some definitions like these, which would affect my calculation result with other projects;<\/div>\n<div class=\"gmail_default\">4. The document (Maxwell NVH, Workshop 1:NVH Analysis Setup in Maxwell 2D) shows the result is 6% difference between Moving1.Torque and MST_Torque (fields calculation), but my result are only 6% and less 50% of the Moving1.Torque, which means fields calculation is 0.27Nm (2023R1), 2.1Nm (2023R2), but the Moving1.Torque is 4.3Nm.<img decoding=\"async\" title=\"No as edge\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/19-01-2024-1705661279-No as edge.png\" alt=\"\"><img decoding=\"async\" title=\"Has as edge\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/19-01-2024-1705661482-Has as edge.png\" alt=\"\"><img decoding=\"async\" title=\"TAU failed\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/19-01-2024-1705661512-TAU failed.png\" alt=\"mesh creation failed if arc set 45deg\"><img decoding=\"async\" title=\"Moving torque\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/19-01-2024-1705661568-Moving torque.png\" alt=\"\"><img decoding=\"async\" title=\"MST_torque\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/19-01-2024-1705661593-MST_torque.png\" alt=\"\"><img decoding=\"async\" title=\"MST_torque equation\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/19-01-2024-1705661660-MST_torque field calculation.png\" alt=\"\"><img decoding=\"async\" title=\"arc setting\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/19-01-2024-1705661685-arc 45deg.png\" alt=\"\"><img decoding=\"async\" title=\"MST_torque R2 result\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/19-01-2024-1705661777-MST_torque R2.png\" alt=\"\"><\/div>\n<div class=\"gmail_default\">&nbsp;<\/div>\n","protected":false},"template":"","class_list":["post-345528","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["337262","186775"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["286"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["345528"],"_bbp_forum_id":["27793"],"_bbp_engagement":["186775","337262"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["346562"],"_bbp_last_active_id":["346562"],"_bbp_last_active_time":["2024-01-25 11:01:25"]},"test":"sli238sheffield-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/345528","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\/345528\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=345528"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
