My set up can be seen in the attached image. I currently only know the inlet gas conditions which are a pressure of 1.5 MPa and a temperature of 750 degrees C. How would i go about defining the outlet gas boundary condition given that i only have inlet conditions ? I&#039;ve seen tutorial videos where the outlet relative pressure is defined as 0, however this doesn&#039;t seem correct in the context of mutli-stage turbines. <\/p>\n<p>I dont have a large amount of knowledge when it comes to the behaviour of gas pressure as it flows through the turbine stages, so any help, advice or guidance would be greatly appreciated, thanks !<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/953\/SZAB1TOB4R96.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/953\/SZAB1TOB4R96.png\" alt=\"boundary condition help.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-167131","topic","type-topic","status-closed","hentry","topic-tag-boundary-conditions","topic-tag-cfx","topic-tag-outlet-boundary-condition"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["934"],"_bbp_likes_count":["0"],"_bbp_subscription":["250484"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["167131"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","250484"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["207808"],"_bbp_last_active_id":["207808"],"_bbp_last_active_time":["2022-03-11 16:47:05"]},"test":"joshua-pretorius123gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/167131","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\/167131\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=167131"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
