I have been trying to simulate broadband noise model acoustics for a certain 2D model and I happen to get these large spots where there is no sound power levels. This issue is only noticeable for acoustics and nothing else. My meshing is correct(&lt;acronym title=&#8221;As far as I know&#8221;&gt;afaik&lt;\/acronym&gt;). I ran and re-ran simulations to fix this but even then it persists, please help me here I would really appreciate it!&lt;br&gt;&lt;br&gt;I notice two major areas of issue, one at the top where there is a large portion of no power, and one near the centreline where there is yet another area of no sound. Why has this happened? I would love to clear this up and fix it&lt;br&gt;&lt;br&gt;I have linked the images for the acoustics and the turbulence Kinetic energy, if anyone requires anything else from the simulation file I am happy to share it.&lt;br&gt;&lt;br&gt;Thank you&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/12\/18-12-2024-1734513805-acoustics 0.65 cf.png\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/12\/18-12-2024-1734513825-turbulnce KE.png\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-397834","topic","type-topic","status-publish","hentry","topic-tag-acousticsimulation-1","topic-tag-broadband-1","topic-tag-c-d-nozzle-2"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["397834"],"_bbp_subscription":["494524","15476"],"_bbp_author_ip":["2a02:cb80:4221:5847:4d4:bd84:3b5e:4fb7"],"_bbp_last_reply_id":["398598"],"_bbp_last_active_id":["398598"],"_bbp_last_active_time":["2024-12-27 09:41:59"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["494524","15476"],"_btv_view_count":["186"],"_bbp_topic_status":["unanswered"]},"test":"praseethsharma453gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/397834","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\/397834\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=397834"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
