cryo man is on a distinguished road
Hello Every Body ;
I want to simulate natural convection around a cylinder that contains the LNG storage to study the behavior of the temperature and velocity in the boundary layer

My geometry is a half cylinder with an axis of symmetry

1)sidewall : type wall , heat flux.
2)background and roof : type wall adiabatic
3)axis of symmetry: type symetry

what are the initial parameters and the boundary conditions that I must enable to define a natural convection

Thank you for your help i reely need!!
