The mesh is regular and continuous (across bodies) and elements are merely divided into two bodies for different materials. I want one of those materials\/bodies to be geometrically linear, while the other geometrically non-linear. The reason is that one of the materials has very low stiffness (7OoM lower than the other), and it exists only because I need those nodes for boundary conditions. The issue is with NLGEOM on for the entire model, the model doesn&#8217;t converge due to last distortions in some elements. I want to either have NLGEOM on for specific nodes or ignore the large distortion check. Is either of those possible?<\/p>\n","protected":false},"template":"","class_list":["post-370227","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["202"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["490"],"_bbp_topic_id":["370227"],"_bbp_forum_id":["27791"],"_bbp_engagement":["490","243039"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["370788"],"_bbp_last_active_id":["370788"],"_bbp_last_active_time":["2024-07-05 15:52:03"]},"test":"rsadiwaclemson-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/370227","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\/370227\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=370227"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
