heat transfer convergence problem on cfx

tomide · July 15, 2014, 13:26

i am trying to model a 2 phase flow in a pipe geometry with bends and valve. i have created my gas fluid as the continuous phase and i used water as a dispersed fluid with particle size 10microns.

i have ran the simulation use good meshing and checked that all my physic is good. every time i run the simulation, the momentum and mass, volume fraction and turbulence parameter all convergence but the heat transfer (energy) never does.

please help!!!
