Those three things are all new to me so I expect it to be tricky. nIn my model, there is a boundary which gets counted as an opening, since I have only modeled a block of air around the fin. I&#8217;m just wondering which of the boundary options in Fluent are equivalent to that in CFX. nI expect I&#8217;ll have lots of other questions, but I&#8217;ve been able to follow tutorials I found online up to this point.n<\/p>\n","protected":false},"template":"","class_list":["post-49133","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["21362"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[" \u0001\u0005i??\r\u0000?:?i\u000b_\u0010?"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["3963"],"_bbp_subscription":["256094"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["49133"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","22555","181966"],"_bbp_voice_count":["3"],"_bbp_reply_count":["30"],"_bbp_last_reply_id":["133190"],"_bbp_last_active_id":["133190"],"_bbp_last_active_time":["2020-11-16 10:22:42"]},"test":"simonhackett"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/49133","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\/49133\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=49133"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
