Until now we have performed our analysis in PATRAN\/NASTRAN. We model the impeller as an assembly of surfaces and the shaft as a 1D line. The mesh ends up as shells and 1D beam elements. To connect the 2D shell impeller mesh to the 1D beam shaft elements we used the RBE2 multi-point constraint. This rigidly linked the shell nodes degrees of freedom to the beam node DOFs.&nbsp;<br \/>I am trying to replicate this in Ansys Mechanical and am hitting a bit of a wall. Ansys seems to have lots of tools for applying remote boundary conditions of different sorts, but I am connecting geometry. Ansys also has &#8216;contact&#8217; tools but they don&#8217;t seem to apply to my need to connect to a single node on a beam element.<\/p>\n<p>The closest I can get to is the Remote Point, but I haven&#8217;t figured out how to connect the master &#8216;point&#8217; to my beam node yet.&nbsp;<\/p>\n<p>Any ideas on what tools to use, or even what general area to search for would be much appreciated.&nbsp;<br \/>Colin<br \/><img decoding=\"async\" title=\"Simplified fan impeller model\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/08\/01-08-2024-1722525126-Screenshot 2024-08-01 160901.png\" alt=\"Shell \/ beam model of fan impeller on shaft\"><\/p>\n","protected":false},"template":"","class_list":["post-374726","topic","type-topic","status-publish","hentry","topic-tag-beams-and-shells","topic-tag-mpc","topic-tag-rbe2"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["131245","58821"],"_bbp_author_ip":["194.168.230.226"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["925"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["374726"],"_bbp_forum_id":["27791"],"_bbp_engagement":["58821","131245"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["374748"],"_bbp_last_active_id":["374748"],"_bbp_last_active_time":["2024-08-01 16:55:56"]},"test":"colin-souzahowden-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/374726","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\/374726\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=374726"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
