The aim is to study the effect of a vibrational force applied on the outer surface of the elastic tube. My question is as follows:<\/div>\n<div>I used the system coupling feature where I created my structural and fluid domains and completed the necessary constraints and boundary conditions for each, then i connected the domains to the system coupling block. For the vibrational force, i used tabulated pressure vs. time data at one frequency. The process was somewhat tedious and seemed impractical, which led me to think there could be a better way to input the vibration. I have access to tabulated pressure data in the time and frequency domains. Moreover, i would like to study the vibrations at specific frequencies as well as the full range of frequencies recorded.<\/div>\n","protected":false},"template":"","class_list":["post-250445","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["273197","58821","267323"],"_bbp_author_ip":["23.192.164.14"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["282"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["250445"],"_bbp_forum_id":["27791"],"_bbp_engagement":["58821","267323","273197"],"_bbp_voice_count":["3"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["250780"],"_bbp_last_active_id":["250780"],"_bbp_last_active_time":["2023-02-21 13:36:39"]},"test":"fia11mail-aub-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/250445","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\/250445\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=250445"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
