Hi everyone,
I'm new in Fluent and I want to know if it is possible to visualize some particular cells. For example in the console I found that I have bad a quality mesh in a particular cell (with its particular coordinates and ID region) and I want to watch but I can't find the command that allows me to do so.

I hope someone can tell me if it's possible or if there is another way to solve my problem,
thanks!

You should be able to create cell registers to visualize these bad cells in Fluent. To create Cell Registers, please go to the Domain Tab. Under the Adapt group, click on Refine / Coarsen... Under Cell Registers, go to New -> Field Variable...

Change Type to 'Cells in Range' and pick 'Field Value of' as 'Mesh' and 'Orthogonal Quality'. Provide the values of Iso-Min and Iso-Max range you would like to visualize and hit Save / Display to inspect. Please see the screenshot below.

To improve the mesh quality, please go to the Meshing step and attempt to improve the quality.

Thanks.

Sorry for the ignorance but the Domain Tab isn't it when I switch to solution? During the meshing the only thing I found about domains is in the Mesh Tab but I can't select the option "Domains...". In short, what I want to know is if it's possible to visualize them during  the meshing.

Thank you very much.

Ahh, you are in Fluent Meshing. My bad. I thought you were in the Fluent Tab.

Please go to the 'Display' tab -> Grid

Please select whether you are looking at Faces or Cells. Change Options to 'Quality', Pick the appropriate 'Quality Measure', provide the Face / Cell Quality Range, Pick the face zone, and then hit Display.

Thanks.
