My initial test case is purely axial flow because issues arise with pressure waves escaping the domain when I add the tangential velocity due to this BC issue! <span>&nbsp;<\/span>Happy to provide more details where requested.<\/span><\/p>\n<p class=\"MsoNormal\"><span lang=\"EN-GB\">&nbsp;<\/span><\/p>\n<p class=\"MsoNormal\"><span lang=\"EN-GB\">Thanks<\/span><\/p>\n","protected":false},"template":"","class_list":["post-313329","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["171423","199"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["193"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["313329"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","171423"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["313607"],"_bbp_last_active_id":["313607"],"_bbp_last_active_time":["2023-10-27 08:57:03"]},"test":"pierceh"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/313329","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\/313329\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=313329"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
