The cylinder is free to move in one direction. The problem is the tube response gets increased by increasing the flow velocity. Which is contrary to real physics. I am wondering if ANSYS is not able to simulate resonance or if I am missing something. <img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/07\/06-07-2023-1688659310-1D_cylinder.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-291933","topic","type-topic","status-closed","hentry","topic-tag-2-way-coupled-fsi","topic-tag-fsi-simulation"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["29207","18096"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["402"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["291933"],"_bbp_forum_id":["27792"],"_bbp_engagement":["18096","29207"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["292067"],"_bbp_last_active_id":["292067"],"_bbp_last_active_time":["2023-07-07 15:02:28"]},"test":"pegah-mehrabianpolymtl-ca"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/291933","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\/291933\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=291933"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
