In this case, both ends of the tube is closed and the tube is flexible (rubber material). Also, the damping is not considered for the water volume inside the tube. I could successfully run the modal acoustics and get the mode shapes. However, I haven&rsquo;t included the FSI layer between the tube and the water volume. Please let me know if I can get the correct mode shapes without defining the FSI.<\/p>\n<p>In another simulation, I have added a contact region between the tube wall and the fluid medium and defined the FSI layer. Simulation was not successful with FSI. It will be great to get your views on this. <\/p>\n<p>&nbsp;Thank you in advance.<\/p>\n<p>Best,<\/p>\n<p>Krishna<\/p>\n","protected":false},"template":"","class_list":["post-165821","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["2304"],"_bbp_likes_count":["0"],"_bbp_subscription":["241208"],"_bbpmt_movedon":["2022-08-26 07:46:37"],"_bbpmt_movedfrom":["27820"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["165821"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","166546"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["203671"],"_bbp_last_active_id":["203671"],"_bbp_last_active_time":["2022-02-08 18:49:27"]},"test":"krishnendu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/165821","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\/165821\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=165821"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
