Do these messages imply the final results are unreliable even if the analysis can be finished eventually?<\/p>\n<p>2) Do the force convergence figure (circled in blue) imply I may have set up too many substeps? It converged well except the two bisection moments (circled in red)&nbsp; i mentioned in 3rd load step.<\/p>\n<p>Appreciate any discussion or explanation!<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/05\/29-05-2023-1685389275-fig5.png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/05\/29-05-2023-1685389288-fig6.png\" alt=\"\"><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-286223","topic","type-topic","status-closed","hentry","topic-tag-ansysworkbench-ansys-staticstructural","topic-tag-substep-2","topic-tag-warning"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["241178","240"],"_bbp_author_ip":["23.39.172.6"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["395"],"_bbp_status":["publish"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["286223"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","241178"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["286232"],"_bbp_last_active_id":["286232"],"_bbp_last_active_time":["2023-05-29 21:46:42"]},"test":"gao13mail-ubc-ca"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/286223","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\/286223\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=286223"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
