static temperature is higher than total temp. in buoyancy problem
 
hi all
I'm simulating fluid flow of molten steel in closed domain using boussinesq approximation because buoyancy is the dominant force in domain ....
problem is solving in steady state mode ....
the problem is that static temperature is higher than total temperature ...for example if total tem. shows 3500k static temp. shows 17000k ....
how can it be possible ?
please help me by your advice to solve it

Is the solution converged? I 'm afraid it's diverging.

hi dude
the solution is not converging and it is main problem in my work .....I assumed that by finding the solution of decreasing the difference between static and total temprature , diverging problem will be solved ....
if u have any experience in modelling this kind of problems - buoyancy - please help me ....
looking forward your guidance
