[mechy]

Hi all
I have simulated flow around a cylinder by OF and FLUENT
In both software, I use a high quality and fine structure mesh which lead to y+<5 over walls and use Kw-sst model

also the setting for OF and FLUENT is as follow

FLUENT BCs:
inlet ========> velocity inlet U=7m/sec k=.2 omega=170
outlet=======> pressure outlet
FLUENT settigs
solver =============> PISO
residual=1e-5


In OF I have used pimpleFoam and setting are as follow

any help will be appreciated
