But higher contact stiffness is also reflected in global coefficients matrix. Higher coefficients make the matrix more ill-conditioned. A PCG solver is sensitive to the ill-conditioned matrices. Thus it will need more iterations which in turn creates longer solution time.<\/p>\n","protected":false},"template":"","class_list":["post-153358","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_edit_lock":["1646191420:4"],"_edit_last":["4"],"_bbp_author_ip":["209.182.204.162"],"_bbp_topic_id":["153358"],"_bbp_forum_id":["27795"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["153358"],"_bbp_last_active_time":["2022-03-02 03:25:09"],"_bbp_engagement":["76744"],"_bbp_voice_count":["1"],"_bbp_reply_count":["0"],"_btv_view_count":["561"],"_bbp_likes_count":["0"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/153358","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\/153358\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=153358"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
