The B-field singularities (or &#8220;hot spots&#8221;) happen because SOLID236 uses true brick shape functions to approximate the edge-flux DoFs. The tetrahedron-shaped SOLID236 or SOLID237 elements do not have this issue.  In comparison, we don&#8217;t see this problem with SOLID117 because, even if it&#8217;s a brick externally, internally it is subdivided into tetrahedras.<\/p>\n","protected":false},"template":"","class_list":["post-170583","topic","type-topic","status-publish","hentry","topic-tag-17-2","topic-tag-general","topic-tag-low-frequency","topic-tag-mechanical-apdl","topic-tag-multiphysics-and-emag-apdl","topic-tag-structural-mechanics"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["2\/6\/2023 20:20"],"_bbp_forum_id":["27789"],"_bbp_author_ip":["209.182.204.162"],"_btv_view_count":["361"],"siebel_km_number":["2045990"],"product_version":["17.2"],"km_published_date":["2017-01-02T20:11:00.000Z"],"family":["Structural Mechanics"],"application_name":["Mechanical APDL"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/170583","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\/170583\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=170583"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
