Reserve flow is no error - it's only a "hint" for you.
You could adjust the back flow in the boundary settings.
In other software I would enable extrusions or "old school" you add it in your model in front of the meshing

/edit: Mesh quality you should anyways.

Hi,

I am trying to solve a cryogenic problem where density of gas changes with temperature. When i change the density property it is showing reverse flow in pressure outlet, but if i use constant density there is no reverse flow.

i am not sure whether it solves your problem or not...
best regards
how do changing of under relaxation factor affect the quality of the results obtained from a fluent simulation
