In the Analysis Settings it says &#8211; The default is to extract the first 6 natural frequencies.<\/p>\n<p><\/p>\n<\/p>\n<p>I have performed Modal Acoustic for a Plate enclosed with a Sphere. I gave the Sphere air properties. Solver Controls were Damped = No and Solver Type = Programm Controlled. <\/p>\n<p>and expected it to give the first 6 natural frequencies of the plate. <\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/W07DWLKSXQYW\/forum-ma-png.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/W07DWLKSXQYW\/forum-ma-png.png\" alt=\"Forum MA.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-52842","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["25151"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[".;?Q"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["4351"],"_bbp_subscription":["231499"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["52842"],"_bbp_forum_id":["27791"],"_bbp_engagement":["58821","184085"],"_bbp_voice_count":["2"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["144887"],"_bbp_last_active_id":["144887"],"_bbp_last_active_time":["2021-03-04 16:45:40"]},"test":"gumang"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/52842","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\/52842\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=52842"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
