I am trying to test a cuboid material with an embedded spheroid object pushing against it. However after running the simulation I get the error:<\/p>\n

A solver pivot warning or error has been detected in the UZ degree of freedom of node 6587 located in Part 1. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues.  Check results carefully. You may select the offending object and\/or geometry via RMB on this warning in the Messages window.<\/p>\n

I need help restricitng the UZ degree of freedom upon the spheroid structure. Any guidance would be appreciated.<\/p>\n","protected":false},"template":"","class_list":["post-355409","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["23.218.248.146"],"_bbp_subscription":["71564","275204"],"_btv_view_count":["1495"],"_bbp_topic_status":["answered"],"_edit_lock":["1710495412:290650"],"_bbp_topic_id":["355409"],"_bbp_forum_id":["27815"],"_bbp_engagement":["71564","275204"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["355458"],"_bbp_last_active_id":["355458"],"_bbp_last_active_time":["2024-03-05 18:14:54"]},"test":"wmhkscducl-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/355409","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/355409\/revisions"}],"predecessor-version":[{"id":355410,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/355409\/revisions\/355410"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=355409"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
