The machine is having all beam connections. I have created a coordinate system from where the lifting will be done and created body-ground spring from there. I have applied gravity downward, and want to do the analysis with weak spring turned off. but i am getting below error, i have checked all the connections, it looks good. I have tried same analysis by fixing the lifting hook, there it is running fine but with the springs it is showing below error. i gave the spring stiffness but showing the below error. please help me with this.&nbsp;&lt;br&gt;&lt;br&gt;&lt;br&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/12-11-2024-1731392750-mceclip0.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-393702","topic","type-topic","status-publish","hentry","topic-tag-mechanicalworkbench-1","topic-tag-ansys-workbench-mechancal","topic-tag-boundary-conditions","topic-tag-mechanical","topic-tag-springmass-1","topic-tag-weak-spring-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["481239","440006"],"_bbp_author_ip":["165.1.236.69"],"_btv_view_count":["290"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["393702"],"_bbp_forum_id":["27796"],"_bbp_engagement":["440006","481239"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["393799"],"_bbp_last_active_id":["393799"],"_bbp_last_active_time":["2024-11-12 13:21:29"]},"test":"sandeep-e-kumarmetso-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/393702","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\/393702\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=393702"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
