The FEMAG/HEM software is dedicated to simulate Sapphire Growth by Heat Exchange Method.
The FEMAG/HEM software provides you with the following:
．Temperature in the sapphire and in all furnace components
．Flow velocity in the sapphire liquid phase
．Crystallization front shape
．Advanced radiation heat transfer in the sapphire
．Thermal stresses (A-axis, C-axis)
