my problem is to generate a heat transfter correlation for the natural convection of liquid metal in 3D over the vertical rod bundles. but i am facing the convergance difficulties in solving the standard K-Epsilon model. the probelm is converging if i treat it as laminar problem but actually it is not. but once if i include the turbulance model it is not converging. can any one help me in reagard of this

Try mesh refinement and different turbulent models
