I am confused and trying to finding this answer. can anyone just tell me what is the procedure to solve this and to get high natural frequencies.<\/p>\n<p><\/p>\n<p>Thank you in advance<\/p>\n","protected":false},"template":"","class_list":["post-36959","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["9134"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0"],"_btv_view_count":["2269"],"_bbp_subscription":["241847"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["36959"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","160648","167346"],"_bbp_voice_count":["3"],"_bbp_reply_count":["13"],"_bbp_last_reply_id":["95104"],"_bbp_last_active_id":["95104"],"_bbp_last_active_time":["2019-09-30 08:33:09"]},"test":"akshaykumar717"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/36959","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\/36959\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=36959"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
