HI;I have a question that when I using heat transfer in solid and lamina flow model to simulate heating a crucible in a silicon furnace, when I setting the heat souce desity equal:6000W/m^3, the simulation is coveraged, The mamxium temperature is 1400K, but when the value is 20000W/m^3, the simumation divergenced. pls help me! How can I solve this question.Thanks.
