My two NS interface turbine and interface volute disapeared but this weird interfaces is now here. However, i can&#8217;t creat a mesh interface with it which is annoying. (also, when shown, it isn&#8217;t yellow as an interface should be but green).<\/p>\n<p>I do not know how to solve this problem, i have tried to modify my CAD, use share in Spaceclaim, use share topology in fluent to &#8216;force&#8217; the creation of an interface between the 2 parts i need, change meshing parameters and naming my surfaces many different ways, but nothing change.<\/p>\n<p>In the attached files, you&#8217;ll find &#8216;stacked pictures&#8217; with :<\/p>\n<ul>\n<li>pics of the Spaceclaim model with NS ans the surfaces i want as an interface<\/li>\n<li>pics of the fluent meshing with everything done to it<\/li>\n<li>pics of fluent solutions highlighting the problem<\/li>\n<\/ul>\n<p>Note :<\/p>\n<ul>\n<li>I have tried to modify my CAD in order to have only 2 &#8216;cylinder&#8217; interface surfaces but it doesn&#8217;t solve the problem. Also for now i do not know if naming all the other surfaces apart from interfaces, inlet and outlet is mandatory for this cfd.<\/li>\n<li>When i open fluent meshing, i have to switch my interfaces from wall to interface in &#8216;update boundary&#8217;<\/li>\n<\/ul>\n<p>Thanks a lot for the time you&#8217;ll take to help me, have a great day ! \ud83d\ude42<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/10\/16-10-2023-1697447084-stacked pictures.png\" alt=\"\"><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-311595","topic","type-topic","status-closed","hentry","topic-tag-cfd-dem","topic-tag-interface","topic-tag-simulation","topic-tag-spaceclaim","topic-tag-unassigned-interface"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["25757","13659"],"_bbp_author_ip":["96.7.218.215"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1248"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["311595"],"_bbp_forum_id":["27792"],"_bbp_engagement":["13659","25757"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["312174"],"_bbp_last_active_id":["312174"],"_bbp_last_active_time":["2023-10-18 19:20:37"]},"test":"louison-ronzeausonceboz-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/311595","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\/311595\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=311595"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
