In this simulation, I aim to capture the dynamics of the valve (opening, equilibrium position, etc.) using a dynamic mesh approach with the Overset method. Despite creating the overset interface and configuring the dynamic mesh with 6 DOF (1 DOF translation) along the valve&#8217;s directional axis, no displacement is observed in the simulation (obtaining a hydrodynamic force of +3.6 N as opposed to a preloaded spring force of -0.3 N should lead to valve opening). A contact detection is performed in the calculation at the guiding zones of the valve. Do you have any insights into why no valve displacement is observed?<\/p>\n<p>Best regards,<\/p>\n<p>Nicolas<\/p>\n","protected":false},"template":"","class_list":["post-299146","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["28811","15180"],"_bbp_author_ip":["23.33.28.204"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["252"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["299146"],"_bbp_forum_id":["27792"],"_bbp_engagement":["15180","28811"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["302103"],"_bbp_last_active_id":["302103"],"_bbp_last_active_time":["2023-08-18 13:10:59"]},"test":"nicolas-le-barbiersafrangroup-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/299146","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\/299146\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=299146"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
