The FEMAG/CZ/OX software is dedicated to the simulation of the Czochralski process and the Kyropoulos process for oxide crystals, such as large diameter sapphire and scintillator crystals.

The FEMAG/CZ/OX is used to design new hotzones and recipes taking into account specific business and technical issues, such as: 

．Growth of large diameter sapphire crystals
．Flow velocity in the sapphire liquid phase
．Crystallization front shape
．Advanced radiation heat transfer in the sapphire
．Design of the furnace hotzone (by a global calculation involving radiation, conduction, convection)
．Gas convection
．Ohmic/Resistive heating and induction heating
．Anisotropic thermal stresses in the crystal
．Multiphysics simulation
