Reduce cells number in fluent
 

Goodmorning.

I read on bibliography that a way to "validate" theresults of a simulation is by refining the mesh, reducing the ceels number and simulating the case.I used a realy thick mess (600000 cells) and i wanna attenuate it and simulate the case again. Can i reducethe number of cells and attenuate the mesh in Fluent? I still havent found a wayto do it.
Thank you in advance

..May be you can try Adapt>Region>Controls>Coarsen or refine.
