I just wanted to know how can I plot the modal damping ratio at each mode number against the system&#8217;s natural frequency?I tried extracting it using the piezoandmems extension, where there there is a solutio otion for the damping modal coefficients but I keep getting this error. I tried this step as recommended by Surya: &#8220;Go to Analysis Settigs &gt; Output Controls and change all the options to Yes&#8221; but nothing worked.<\/p>\n<p>&nbsp; <img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/08-08-2023-1691516296-Screenshot 2023-08-07 181452.jpg\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-298814","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["274190","20905","88","50680","240"],"_bbp_author_ip":["23.206.193.150"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["3453"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["298814"],"_bbp_forum_id":["27791"],"_bbp_engagement":["88","240","20905","50680","274190"],"_bbp_voice_count":["5"],"_bbp_reply_count":["17"],"_bbp_last_reply_id":["301226"],"_bbp_last_active_id":["301226"],"_bbp_last_active_time":["2023-08-13 16:01:39"]},"test":"ucembaaucl-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/298814","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\/298814\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=298814"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
