If you are solving a rotating problem, your fluid domain should be set up as a rotating domain, while the solid domain should be stationary. Do not create any wall boundary conditions on these surfaces. Create fluid-solid domain interfaces in the usual way. Once you have created the domain interface, you will see that CFX-Pre has automatically created some boundary conditions for the fluid and the solid side. You can then edit the fluid side boundary condition and set a wall velocity, a rotating wall, or leave the walls as stationary as required. A stationary wall is always stationary with respect the local domain.<\/p>\n","protected":false},"template":"","class_list":["post-164592","topic","type-topic","status-publish","hentry","topic-tag-4424","topic-tag-cfx","topic-tag-fluid-dynamics","topic-tag-general-cfx"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["3-15-2023  20:20:39"],"_bbp_forum_id":["27796"],"_bbp_author_ip":["23.56.168.180"],"_btv_view_count":["708"],"siebel_km_number":["384342"],"product_version":["16"],"km_published_date":["2005-03-04T00:00:00.000Z"],"family":["Fluid Dynamics"],"application_name":["CFX"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/164592","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/164592\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=164592"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
