Fluent does have a 2d solver so then works on faces rather than volumes.&nbsp;&lt;\/p&gt;&lt;p&gt;Flattening to true 2d in Fluent may break the rotational periodic option that you&rsquo;re trying to mimic. You may need to create a curved 3d model but set inner &amp; outer annular faces as symmetry and have only one cell in the radial coordinate. You can then follow the turbo examples for the rotor-stator configuration. Note, check the interface settings to ensure you&rsquo;re retaining the data on both sides of the interface: you don&rsquo;t want any averaging!&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-303873","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/303873","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/303873\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=303873"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
