I would like to use k-e model to make a initial condition. then, LES and acoustic model are spllied to calculate the sound generated by flow in the branch.&nbsp;<\/p>\n<p>In order to do that, I want to fine mesh around the branch entrance, would you tell me how to do that?<\/p>\n<p>Additionally, do you have any idea about the entrance length of the pipe? In my calculation, the entrance length was 14ft but it would be difficult for the computational cost. So I tryed to use 9 in (this is randomly decided) as a first try.&nbsp;<\/p>\n<p>Thank you.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/06\/04-06-2024-1717461973-ansys1.png\" alt=\"\" width=\"912\" height=\"309\"><\/p>\n","protected":false},"template":"","class_list":["post-369686","topic","type-topic","status-closed","hentry","topic-tag-circular-pipe","topic-tag-mesh"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["264444"],"_bbp_author_ip":["23.216.133.155"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["164"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["369686"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","264444"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["370122"],"_bbp_last_active_id":["370122"],"_bbp_last_active_time":["2024-07-02 13:17:03"]},"test":"hamanaka-ytamu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/369686","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\/369686\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=369686"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
