The connection between the two bodies should be modeled as a constant 6&#215;6 stiffness matrix between two remote points.&nbsp;&lt;\/p&gt;&lt;p&gt;The modal analysis was performed with MPC184 elements whose formulation is not supported by the geometry condensation feature. Using a bushing connection or a COMBI250 element is not sufficient because it covers only the diagonal terms of the stiffness matrix and in my case the off-diagonal terms do play an important role.&lt;\/p&gt;&lt;p&gt;Is there anything I could do to overcome this issue in Workbench?&nbsp;&lt;\/p&gt;&lt;p&gt;Thanks in advance!&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-397311","topic","type-topic","status-publish","hentry","topic-tag-mechanicalworkbench-1","topic-tag-bushing-1","topic-tag-condensation","topic-tag-connection","topic-tag-mpc184-1","topic-tag-remote-points","topic-tag-stiffness-matrix"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27791"],"_bbp_topic_id":["397311"],"_bbp_author_ip":["147.102.131.39"],"_bbp_last_reply_id":["398237"],"_bbp_last_active_id":["398237"],"_bbp_last_active_time":["2024-12-23 02:29:13"],"_bbp_reply_count":["10"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["4"],"_bbp_engagement":["80011","240","58821","495914"],"_btv_view_count":["529"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["240","58821","80011","495914"],"_edit_last":["52629"],"_bbp_revision_log":["a:1:{i:397577;a:2:{s:6:\"author\";i:52629;s:6:\"reason\";s:0:\"\";}}"]},"test":"mc20008mail-ntua-gr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/397311","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\/397311\/revisions"}],"predecessor-version":[{"id":397577,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/397311\/revisions\/397577"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=397311"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
