[Turbulence]

Hi Everyone,
I am currently trying to simulate free round jet flow. If the jet inlet diameter is d, my computational domain is a cylinder which is 250d in axial direction and has a diameter of 400d. PFA the image of background mesh with the geometry. Earlier I had problem of inlet pipe completely disappearing. So I chose a background mesh of this shape.
Now my inlet looks good, but my computational domain(the big cylinder) is not meshed.
Can anyone help me in this regard.
Thanks
Turbulence.
