I specified an outer domain enclosing all the geometry and an inner domain enclosing only the quadcopter propeller. I want to model the acoustics without any airflow (vacuum-like) and obtain the data comparing Sound Pressure Level (dB) vs. Frequency. Is this setup sufficient? This is for near-field acoustics btw.&nbsp;<\/span><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/29-02-2024-1709249631-Geom.PNG\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-354697","topic","type-topic","status-closed","hentry","topic-tag-acousticsimulation-1","topic-tag-acoustics","topic-tag-aeroacoustics","topic-tag-aerodynamics","topic-tag-aerospace-engineering-1","topic-tag-air-flow","topic-tag-computational-fluid","topic-tag-fluid","topic-tag-fluid-domain-1","topic-tag-propeller-1","topic-tag-propeller-rotation-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["31610"],"_bbp_author_ip":["23.218.248.135"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["227"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["354697"],"_bbp_forum_id":["27790"],"_bbp_engagement":["31610"],"_bbp_voice_count":["1"],"_bbp_reply_count":["0"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["354697"],"_bbp_last_active_time":["2024-02-29 23:41:45"]},"test":"jflores2743sdsu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/354697","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/354697\/revisions"}],"predecessor-version":[{"id":354764,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/354697\/revisions\/354764"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=354697"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
