Do I need to try with R 2 version?&lt;br&gt;I would also like to bring your attention to one more issue:&lt;br&gt;Geometry and Boolean Operations: In my study, I created a flow domain around the geometry, and I performed boolean subtraction\/suppression operations successfully.&lt;br&gt;&lt;br&gt;Meshing Issue: After importing the geometry into Fluent for meshing, I noticed that just after creating the surface mesh, the console window displays a message stating, &ldquo;The region consists of 1 Fluid and 1 void region.&rdquo; This differs from the examples in the Ansys innovation courses, where only one fluid region and no voids are expected.&lt;br&gt;&lt;br&gt;Comparison with ANSYS 2020 R1: To verify, I performed the same procedures in ANSYS 2020 R1, and I obtained the expected result mentioned in the innovation courses, i.e., &ldquo;The region consists of 1 fluid region with no voids.&rdquo; However, when the same file is transferred to ANSYS Fluent version 2023 R1, the message window still identifies 1 fluid region and 1 void.&lt;br&gt;&lt;br&gt;I would like to know whether this is because of Ansys versions or Do i need to take of all this.&lt;br&gt;When I ignored the console message and proceeded with describing the geometry I had one only 1 fluid region. I received a warning message in the console window&rdquo; The region cannot cannot be deleted as it is completely enclosed by another region&rdquo;.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-308366","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/308366","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\/308366\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=308366"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
