Hello guys

I'm trying to solve a problem in Solid Works CFD, Liquid Nitrogen stratification (Cryogenics) . In a tank liquid nitrogen-filled up to 80% (LN2 77k) Tank outside temp is something about 293k Due to ambient temperature after few hours tank will get conduct and inside liquid get convective. Just to understand the fluid convective flow due to buoyancy.

Could you please help me out boundary condition set up for this problem in Solid Works CFD...

Thank u
