I also have a frequency response data (acceleration of a point on my structure) from the experiment. The structure was subjected to harmonic excitation at various frequencies while acceleration was measured. Now I would like to now, is it possible to calibrate my damping coefficients which I have parameterized, so that response matches my experimental data. In the sense that I input a few accelerations measured at different frequencies in the experiment and than use some kind of optimization algorithm that ANSYS provides to calibrate my model. If so, how?nI appreciate your answers.nn<\/p>\n","protected":false},"template":"","class_list":["post-50890","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["23144"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["T)^M"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["789"],"_bbp_subscription":["231790"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["50890"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","184550"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["137686"],"_bbp_last_active_id":["137686"],"_bbp_last_active_time":["2021-01-05 15:45:46"]},"test":"biokill"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/50890","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\/50890\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=50890"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
