When Ansys solves F=Ku, does it directly solve the nodal forces and displacements, or does it solve at the Gauss points and then extrapolates to the nodes? I understand that stress and strain are evaluated at the Gauss points and are extrapolated, but not too sure on displacement.<\/p>\n<p>All my references say F=Ku is solved for the nodes. If that&#039;s the case then I gotta dig deeper as to why\/how stress and strain are evaluated at the Gauss points. I understand there&#039;s a bit of numerical integration happening at the Gauss points, but the whole process isn&#039;t so clear to me yet.<\/p>\n<p>Thank you!<\/p>\n","protected":false},"template":"","class_list":["post-162757","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["2814"],"_bbp_likes_count":["0"],"_bbpmt_movedon":["2022-08-26 07:55:34"],"_bbpmt_movedfrom":["27820"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["162757"],"_bbp_forum_id":["27791"],"_bbp_engagement":["490","185320"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["193790"],"_bbp_last_active_id":["193790"],"_bbp_last_active_time":["2021-10-04 16:44:33"]},"test":"greg2835"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/162757","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\/162757\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=162757"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
