Simulation of crystal growth processes

Knowing precisely the thermal behaviour of the material being manufactured is an essential need to develop new processes and to adapt or change equipment settings, as well as optimize operating points during industrial production.

  • To know how precise are thermal simulations.
  • Accounting for liquid convection

Simulations undertaken

In the present case, 2D axis-symmetrical and 3D stationnary simulations were done at the beginning and at the end of the solidification process.

Comparisons between solutions to improve the process
