I have a flow domain and there is a blade which is extracted from the flow domain with the Boolean command. I selected the faces of the blade in the name selection. nWhat should I choose for the boundary conditions of this blade if I&#8217;m using MRF method(blade is a wall obviously)? Should I leave it as it is which is basically stationary wall\/relative to cell zone? Or should I change it to moving wall\/relative to cell zone and give 0 rpm rotation to it? nI read that when we are using MRF approach, it&#8217;s as if we&#8217;re standing on the blade and therefore blade is stationary for us and everything else is rotating. I would really appreciate if someone can clarify this boundary condition.nBest Regards,<\/p>\n","protected":false},"template":"","class_list":["post-51912","topic","type-topic","status-closed","hentry","topic-tag-mrf"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["24190"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["_\n?b"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1127"],"_bbp_subscription":["231305"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["51912"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","183673"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["141264"],"_bbp_last_active_id":["141264"],"_bbp_last_active_time":["2021-02-04 15:48:28"]},"test":"metin"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/51912","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\/51912\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=51912"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
