Unlike the 18.2 and 19.0 versions of Ansys, there is no harmonic acoustic under 18.1 version. The versions below need to do download ACT to perform the sound analysis, and as mentioned above, I wanted to proceed with the acoustic analysis in Ansys 18.1 version after downloading ACT 18.0 version. However, the harmonic surface velocity does not working. In the latest version, if I specify the geometry, it is solved immediately. I want to know why it is not in 18.1 version.<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/703f4fb7-b143-44b8-93d5-a8e80126c1cb\/96556deb-0f5a-46bc-a856-a8f3004f7058_not-working-surface-velocity.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Attached is an archive of ansys 18.1 to be analyzed.<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-29405","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["1574"],"_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","0","0","0"],"_btv_view_count":["5137"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["29405"],"_bbp_forum_id":["27784"],"_bbp_engagement":["240","157104","177541"],"_bbp_voice_count":["3"],"_bbp_reply_count":["16"],"_bbp_last_reply_id":["115446"],"_bbp_last_active_id":["115446"],"_bbp_last_active_time":["2020-05-22 19:15:31"]},"test":"unitnatis"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/29405","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\/29405\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=29405"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
