Is it accurate to say that the buoy is constrained to only heave in reality?<\/p>\n<p>However, in the frequency domain, when calculating the Response Amplitude Operator (RAO), there is no deactivation option. Does this mean that our buoy has degrees of freedom in different directions?<\/p>\n<p>What should I do to introduce a joint that allows our buoy to only have motion in the Z direction? Additionally, what types of joints should I use to incorporate a damper in the system, as shown in the attached photo<button class=\"flex items-center gap-1.5 rounded-md p-1 text-xs text-token-text-tertiary hover:text-token-text-primary md:invisible md:group-hover:visible md:group-[.final-completion]:visible\"><\/button><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/12-03-2024-1710209570-mceclip0.png\" width=\"228\" height=\"191\"><\/p>\n","protected":false},"template":"","class_list":["post-356532","topic","type-topic","status-closed","hentry","topic-tag-ansys-aqwa","topic-tag-ansysaqwa","topic-tag-aqwa","topic-tag-joints-ansys-aqwa-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["338493","180344"],"_bbp_author_ip":["23.206.193.154"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1016"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["356532"],"_bbp_forum_id":["27791"],"_bbp_engagement":["180344","338493"],"_bbp_voice_count":["2"],"_bbp_reply_count":["9"],"_bbp_last_reply_id":["357550"],"_bbp_last_active_id":["357550"],"_bbp_last_active_time":["2024-03-18 09:42:59"]},"test":"r-abbasiuq-edu-au"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/356532","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\/356532\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=356532"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
