Please resolve the issue and try again.&#8221;   This error message occurs, because a certain face or domain cannot be used for more than one &#8220;Named Selection&#8221; within a Fluent mesh as Fluent is using the &#8220;Named Selections&#8221; to define the cell zones and boundary faces, respectively.  You can show the problematic overlapping geometries by right clicking on the &#8220;Mesh&#8221; branch of the tree and choosing &#8220;Show&#8221; -> &#8220;Geometry in Overlapping Named Selections&#8221;. In addition to that you can automatically repair the problematic &#8220;Named Selections&#8221; by right clicking on the &#8220;Named Selections&#8221; branch and choosing &#8220;Repair Overlapping Named Selections&#8221;. But attention, this might result in a not useful boundary face setup. Hence, it is suggested to repair the problematic &#8220;Named Selections&#8221; manually.<\/p>\n","protected":false},"template":"","class_list":["post-167240","topic","type-topic","status-publish","hentry","topic-tag-19-1","topic-tag-fluid-dynamics","topic-tag-general","topic-tag-meshing"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["5\/4\/2023 20:20"],"_bbp_forum_id":["27796"],"_bbp_author_ip":["209.182.204.162"],"_btv_view_count":["1281"],"siebel_km_number":["2055970"],"product_version":["19.1"],"km_published_date":["2018-08-16T00:00:00.000Z"],"family":["Fluid Dynamics"],"application_name":["Meshing"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/167240","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\/167240\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=167240"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
