I am using ANSYS 2023 R1 Magnetostatic to simulate the magentic flux density generated by the dual stators in an axial flux permanent magent generator. The backing plates (the big rings) are steel, the poles are all Nd35 magnets, and the enclosure is air. I have applied my own coordinate system and defined pole directionality for all the magnets based on this. I have applied the magnetic flux parallel boundary condition to the cylindrical enclosure (all 3 faces of this body) and have attempted to run the simulation both with and without total magnetic flux density assigned to the solution. However, whenever I attempt to run the solver it gets to about 10% of the solution within a few seconds, but then I get a fatal error. I am wondering if the computer I am using is not equipped to handle this simulation. The mesh size for the backing plates and magnets is 5 mm and for the enclosure it is 10 mm, both using the automatic mesh method. I have green checks through the whole model tree up until the solution (when it fails). I am wondering if anyone has any insight they can provide. I would be much appreciated. I have attached pictures of the model, model tree, and solver report below for reference. The error reads:<\/p>\n<div id=\"paraDiv\">\n<p id=\"paragraphData\" class=\"paragraphText\" style=\"font-size: 12px;display: inline\">*** ERROR ***&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CP =&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.594&nbsp;&nbsp; TIME= 16:03:01<br \/>&nbsp;The option of C on the MP command is either not available for this&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br \/>&nbsp;version of Ansys or the appropriate product was not selected for this&nbsp;&nbsp; <br \/>&nbsp;session.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br \/>&nbsp; Contact your Ansys support person for more information.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n<\/div>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/02-01-2024-1704230992-Model Tree.jpg\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/02-01-2024-1704231008-3D Model.jpg\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/02-01-2024-1704231397-Solver Report Screenshot.jpg\" alt=\"\"><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-342808","topic","type-topic","status-closed","hentry","topic-tag-error","topic-tag-flux","topic-tag-magnet"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["54291","50680"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["540"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["342808"],"_bbp_forum_id":["27793"],"_bbp_engagement":["50680","54291"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["343242"],"_bbp_last_active_id":["343242"],"_bbp_last_active_time":["2024-01-04 19:23:18"]},"test":"adam-sandahluconn-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/342808","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\/342808\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=342808"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
