Hi all, has anyone come up with a solution to Martin's last query? 

I have the same issue with selecting multiple faces on a solid that are located adjacent to eachother but within curving profiles that wind their way both axially and circumferentially on a cylinder.  I need to provide local sizing to these faces and as such had created a named selection for them in Space Claim - by the same process Martin cited in his last post. 

If I import the facetted body into the solver (I am using Fluent for my application), I maintain all the named selections I created but am also provided with a 'failed' surface which is comprised of the entirety of the facet body when the surface is inspected in the preview window. 

I am using the watertight workflow in 2022r2.  For my analyses, I am restricted to using this version - I cannot migrate to 2023r1 to make use of what I believe has a solution to the issue I am having with the facetted body moving into the solver. 

The only method in which I am able to correctly identify the surfaces and the named selections that they belong to as well as identification of the volume enclosed by the surfaces is to migrate the geometry into the watertight meshing as a solid.  When I convert the faceted body to a solid in space claim, I lose all the named selections I created in the facetted body.  Due to the tens of thousands of faces all within such an awkward to access profile, it is grossly inefficient the attempt to pan-rotate-zoom-ctrl&click as often as would be required to select each face.

Any guidance would be hugely appreciated - even if it would be to give insight to the 'failed' surface created on the facetted geometry in watertight geometry - update boundaries stage.

Thanks for any help.
