In the begining the model had some frictionless contact that had to be changed by No-Separation contacts. The model also has fixed supports and compression only supports. I tried to solve the model but it was impossible, so I decided to change the compression only supports for displacement constraints, setting X,Y free and Z=0, but I know they aren&acute;t equal. Does it exist some way to model a compression-only support with&nbsp;displacement constraints, or is it possible to solve the model using compression only support?<\/p>\n<p>Thank you in advance,<\/p>\n<p>A.O.G.<\/p>\n","protected":false},"template":"","class_list":["post-167739","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["4532"],"_bbp_likes_count":["0"],"_bbp_subscription":["252015"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["167739"],"_bbp_forum_id":["27791"],"_bbp_engagement":["99","252015"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["209640"],"_bbp_last_active_id":["209640"],"_bbp_last_active_time":["2022-03-28 07:18:36"]},"test":"asier-olloquiegui-gomezalumnos-upm-es"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/167739","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\/167739\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=167739"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
