I have given the EM loss boundary condition in Icepak for the model. However, meshing is not taking place and the software crashes. I tried coarse mesh and this crashes by mentioned warnings like &#8216;this geometry does not have mesh&#8217;. I tried healing and simplifying the model, even then no chance. I imported the geometry from AutoCAD as an iges file. some portion of the geometry is from the iges file and the remaining, I copy pasted from an already existing .stp file with in the ansys window. and then deleted the unnecessary. I did this because, when importing from AutoCAD, the objects are imported as sheets and not solids\/ volumes in ansys. what do you suggest?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-441301","topic","type-topic","status-publish","hentry","topic-tag-2022-r1-1","topic-tag-AEDTICEPAK-1","topic-tag-ansys-q3d-extractor","topic-tag-meshing","topic-tag-powerelectronics-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27793"],"_bbp_topic_id":["441301"],"_bbp_subscription":["594409","2688"],"_bbp_author_ip":["137.205.72.6"],"_bbp_last_reply_id":["441474"],"_bbp_last_active_id":["441474"],"_bbp_last_active_time":["2025-09-15 16:17:39"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["594409","2688"],"_btv_view_count":["3392"],"_bbp_topic_status":["unanswered"]},"test":"usha-manasa-ammuwarwick-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/441301","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\/441301\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=441301"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
