The global heat transfer simulation takes into account :
- radiation and conduction in the overall furnace,
- convection inside melt phase.
"Global" means that all the furnace elements and all the heat transfers are taken into account in the computation.

| The heat transfer governs the process. The species distributions in the ingot, the heating power dissipation, the ingot cooling depends on the heat transfer. Therefore, the precise knowledge of the global heat transfer is a key data for process optimization. |
|
| The temperature computation is a starting point. Based on this result, you can compute the heat fluxes, the thermal gradients, the thermal stresses, the point-defect distribution. |

| Global heat transfer. Temperature isolines are separeted by 50 K. |

The melt convection computation is needed to compute:
- an accurate interface shape required for defect distribution computation
- the dopant distribution along the solidification interface, a preliminary data to computation of the dopant distribution in the crystal.
