My problem is that Fluent assigns the label &#8220;ff&#8221; to my fluid region when generating the surface mesh but I need to change that since I am having name clashes downstream in the workflow. I have seen on the internet that one solution (at least in Fluent meshing v15) was to generate a material point with a name so when the regions are automatically generatedm the material point name will be assigned. I have generated a material point named fluid_interior (inside the domain) and this is my workflow before generating the surface mesh:&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/24-07-2026-1784887316-mceclip1.png\" \/>&lt;\/p&gt;&lt;p&gt;And this right after:&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/07\/24-07-2026-1784887633-mceclip2.png\" \/>&lt;\/p&gt;&lt;p&gt;As you can see, Fluent ignores the material point name and generates a volumetric region whose name is &#8220;ff&#8221; which gives me issues later on when assigning BCs and zone types. How can I change this behaviour and assign the region name before its creation?
