An interior\/wall\/inlet etc is part of the mesh as it makes up part of the geometry.&nbsp;&lt;\/p&gt;&lt;p&gt;User surfaces aren&#8217;t transferred, so you need to create it where ever you want it. We can use the surface integrals in Fluent to get the mass flow, but if it&#8217;s a value to want to know before you start the modelling I&#8217;d break the domain up to include that surface in the original model. So your domain might contain multiple faces in geometry that are connected to ensure a conformal mesh.&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-382494","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/382494","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\/382494\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=382494"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
