I try to create secondary flow system (cavities for stators). After inputing cavity CAD , creating entity and assigning names I have a problem with cavity inlet and outlet definition. Normally, under geometry branch, you define boundary conditions for the cavity (wall, hub\/shroud interface). Then, if the cavity inlet\/outlet is in the inlet\/outlet domain you click &#8220;automatically manage opening region&#8221; and it&#8217;s automatically cut to corresponding interfaces that can be later managed in CFX. Here I have a tight space with only passage inlet\/outlet region. When I try to do the same as above, the following error occurs : &#8221; Region AUTOINTERFACETE2D both points lie in the blade passage&#8221;. When I move the passage outlet before the cavity outlet, there is no error, the automatic region in hub tab is created, however under 3Dmesh branch there is no corresponding region created &#8211; so I cannot use it later in CFX! (and there is nothing between passage outlet and geometry outline)&lt;br&gt;I think I tried all the solutions that came to my head &#8211; played around with geometries, but no success.&lt;br&gt;Does anyone have an idea what might be the issue?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-404343","topic","type-topic","status-publish","hentry","topic-tag-turbomachinery"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27790"],"_bbp_topic_id":["404343"],"_bbp_subscription":["501611","68667"],"_bbp_author_ip":["2001:4ca0:2fff:2:5:3:0:25"],"_bbp_last_reply_id":["405002"],"_bbp_last_active_id":["405002"],"_bbp_last_active_time":["2025-01-15 01:17:28"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["501611","68667"],"_btv_view_count":["232"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1736458502:501611"]},"test":"4780d9070f7fc8052762969d59e58d96c73c634c"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/404343","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\/404343\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=404343"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
