Zone Creation To Existing Fluent Mesh
 

Hello

I want to create some surfaces on ICEM to an existing fluent mesh. I am working in a coal combustion simulation, the geometry has 3 concentric cylinders, with one of them having a conical increase of area. I want to project my inlet through along different axial positions. The thing is that doing this via fluent I get undesired areas, therefore I manually created and meshed these zones in ICEM.

When I finally create the new mesh and import it to Fluent again, I have this error

Skipping Zone ### (not referenced by grid)

Could anyone help me?

Hello Alain,

One suggestion I have found elsewhere online is to use the Imprint features in Fluent; go to Surface > Create > Imprint then click "Help" for more details, or just look in the manual. The reason for this is that Fluent will recognize the volumes, and faces that bound those volumes. It won't see (and will skip) floating faces.

Thank you @aero_head

I later noticed the imprint surface option as you suggest. The thing is that it just inserts floating surfaces into the domain that are not referenced by the grid to sample flux reports (which was my objective then).

What came as a solution for me was to re-mesh the desired section into various intervals separated by interfaces, which I later defined as interior cells. Then I was able to sample gas and DPM mass flow rates.

Hello Alain,

I am glad you were able to solve your issue. Thanks for posting the solution you found.
