I have tried improving the orthogonality and it finally has increased from 0.0081 to 0.0586 at the cost of cell counts increased by 64%. The convergency has slightly improved in inviscid single phase flow. But I think maybe it&#8217;s not satisfying enough for an engineering problem that the the ratio of net mass flow rate of inlet and outlet is around 2.65%.&nbsp;&lt;\/p&gt;&lt;p&gt;I&#8217;m not exactly understand the meaning of the &#8220;pave mesh&#8221;. Do you means a hybrid mesh strategy should be used? Using unstructured mesh near the shoreline region and finally append the structured and unstructured mesh file in Fluent? I haved thought about this solution. If so, ICEM and Fluent meshing are reqiured and interface may be applied, I think. I have tried using Fluent meshing but it seems that hexahedral mesh with extremely high aspect ratio (~1000) in the bulk domain is not realizable in order to reduce the cell counts as much as possible.&nbsp;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Sincerely thanks for your helpful advice.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-396199","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/396199","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\/396199\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=396199"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
