I wanted to make a structural analysis for my self-made car jack during which I would lift it up on 3 chosen heights and determine how Force of 2 Tons works on my object. All the components I made in Autodesk Inventor and assembled them in Spaceclaim. Howoever the worst part came when I opened Workbench. Cause I have no idea which parts I should combine with which joint or contact. I used Bonded to combine arms with upper base and lower base and to combine arms with upper bases I used Joints Revolute.&lt;\/p&gt;&lt;p&gt;Size element for entire body except arms = Default (11,739 mm)&lt;\/p&gt;&lt;p&gt;Size elements of arms = 1,2 mm&lt;\/p&gt;&lt;p&gt;Entire construction is made of Structural Steel&lt;\/p&gt;&lt;p&gt;After entire analysis I get 3 warnings:&lt;\/p&gt;&lt;p&gt;1) &nbsp;One or more MPC or Lagrange Multiplier formulation based contact regions or remote boundary conditions may have conflicts with other applied boundary conditions or other contact or symmetry regions. This may reduce solution accuracy. For MPC based remote points, setting the relaxation method may help eliminate overconstraint. Tip: You may graphically display FE Connections from the Solution Information Object for non-cyclic analysis. Refer to Troubleshooting in the Help System for more details.&lt;br&gt;&lt;br&gt;&lt;\/p&gt;&lt;p&gt;2) Joints are being used in the current analysis with Large Deflection turned Off. &nbsp;Thus, only linearized joint behavior will be considered. &nbsp;If finite rotation and large deflection effects are to be considered, please turn on Large Deflection.&lt;\/p&gt;&lt;p&gt;3) Two or more remote boundary conditions are sharing a common face, edge, or vertex. &nbsp; This behavior can cause solver overconstraint and is not recommended, please check results carefully. &nbsp;You may select the offending object and\/or geometry via RMB on this warning in the Messages window.&lt;\/p&gt;&lt;p&gt;What should I do in this situation to fix it and make it work ? What kind of joints or contacts should I choose for which part of car jack ?&lt;\/p&gt;&lt;p&gt;PS: There is no intervention beetween parts and the clearance is ok.&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/25-11-2024-1732529780-glupota.jpg\" alt=\"\" \/>&nbsp;&lt;\/p&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-395145","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["21030","17457","58821"],"_bbp_author_ip":["94.254.152.238"],"_btv_view_count":["254"],"_bbp_topic_status":["unanswered"],"_edit_last":["58821"],"_bbp_revision_log":["a:1:{i:395157;a:2:{s:6:\"author\";i:58821;s:6:\"reason\";s:0:\"\";}}"],"_bbp_topic_id":["395145"],"_bbp_forum_id":["27791"],"_bbp_engagement":["17457","21030","58821"],"_bbp_voice_count":["3"],"_bbp_reply_count":["20"],"_bbp_status":["publish"],"_bbp_last_reply_id":["395544"],"_bbp_last_active_id":["395544"],"_bbp_last_active_time":["2024-11-27 12:21:26"]},"test":"kubatycjaninteria-pl"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/395145","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\/395145\/revisions"}],"predecessor-version":[{"id":395157,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/395145\/revisions\/395157"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=395145"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
