The tube models a fire hose with isotropic elasticity consisting of an elastic modulus of 60 MPa and Poisson ratio of 0. The goal is to simulate the upper bar clamping the hose shut with pressure in the tube,&nbsp;eventually bringing the two bars together while keeping them in parallel. To do this, we applied a 300 psi pressure normal to the surface&nbsp;in the tube and a displacement of 1.5 inches on the top face of the upper bar. The faces of the ends of the tube and the bottom face of the lower bar are fixed supports. However, we are experiencing an issue with the solver regarding boundary conditions and large deflection,&nbsp;and do not receive results. Our question is how to model the assembly with the correct boundary conditions for the simulation to run.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/225\/9KYOVPS7YAYC.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/225\/9KYOVPS7YAYC.png\" alt=\"hose_forces.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-158745","topic","type-topic","status-closed","hentry","topic-tag-ansys-workbench","topic-tag-boundary-conditions","topic-tag-static-structural"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_view_count":["13303"],"_bbp_likes_count":["0","0"],"_bbp_forum_subforum_count":["0"],"_btv_view_count":["1011"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["158745"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","185297","197685"],"_bbp_voice_count":["3"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["179541"],"_bbp_last_active_id":["179541"],"_bbp_last_active_time":["2021-05-25 03:09:59"]},"test":"dtocolucsd-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/158745","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\/158745\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=158745"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
