Hello everyone,<\/span><\/p>\n

I’m working on an numerical analysis of transient flow past two rotating circular cylinders at Re=100 in Ansys Fluent. Firstly, I ran the first case with the only one cylinder rotating (the other one was stationary) and I got the correct results. But, when I defined extra the second cylinder as a moving wall, I got the following message: <\/p>\n

<\/span><\/p>\n

WARNING:<\/a> The<\/a> wall<\/a> motion<\/a> has<\/a> a<\/a> significant<\/a> normal<\/a> component<\/a> on<\/a> 78<\/a> faces<\/a> of<\/a> face<\/a> zone<\/a> 10.<\/a><\/p>\n

The<\/a> maximum<\/a> angle<\/a> between<\/a> the<\/a> velocity<\/a> and<\/a> face<\/a> surface<\/a> is<\/a> 89.2<\/a> deg<\/a> at<\/a> (<\/a> 4.221e-01,<\/a> 4.926e-01,<\/a> 0.000e+00).<\/a><\/p>\n

The<\/a> tolerance<\/a> for<\/a> this<\/a> check<\/a> is<\/a> controlled<\/a> by<\/a> the<\/a> rpvar<\/a> ‘wall\/vnormal-tolerance’.<\/a><\/p>\n

Please<\/a> check<\/a> your<\/a> setup.<\/a> This<\/a> warning<\/a> will<\/a> not<\/a> be<\/a> written<\/a> again.<\/a><\/p>\n

I have set the motion as “relative to adjacent cell zone” in both boundary conditions. (I don’t know if this is related somehow.)
The reference frame has been defined at the center of the one cylinder.
Does anyone know something about this warning and what probably can I do to fix it?
Thank you in advance!<\/span><\/p>\n","protected":false},"template":"","class_list":["post-365080","topic","type-topic","status-closed","hentry","topic-tag-ansys-cfd-1","topic-tag-Ansysfluentsetuperror-1","topic-tag-fluent-setup-1","topic-tag-tolerance"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["60901","730"],"_bbp_author_ip":["23.216.133.155"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1892"],"_bbp_topic_status":["answered"],"_bbp_topic_id":["365080"],"_bbp_forum_id":["27792"],"_bbp_engagement":["730","60901"],"_bbp_voice_count":["2"],"_bbp_last_reply_id":["365361"],"_bbp_last_active_id":["365361"],"_bbp_last_active_time":["2024-05-03 09:32:58"]},"test":"na18393075uniwa-gr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/365080","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/365080\/revisions"}],"predecessor-version":[{"id":365924,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/365080\/revisions\/365924"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=365080"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
