Boundary condition for free convection
What are the suitable boundary condition for free convection in starccm+. I am trying to simulate natural convection of a sphere in open atmosphere. so my thought was that freestream conditon all around with very low velocity and boundaries at a very large distanec would work but it dooesnt seem to give physical results. Any suggestions.I have also already triend with adiabatic walls at a large distance.
any suggestions or your experiences with such problems will be appreciated.
