Solution in FLuent is giving weird results
 
Working on K-Epsilon realizable model with energy equation.
Foe the first 22000 iteration I switched off the energy equation. after 22000 iteration I solved for energy only. Now just after 60 iteration I am getting negative heat transfer coefficients , residual rose back to 1e-02 from 1e-07.

??????
What could possibly the reasons
Tried altering boundary condition. Again during simulations I am getting that temperature has been limited to some value (say 1 or 5) in certain number of cells.
?????
