Abstract: With the Ribbon Growth on Substrate (RGS) technology, a
new crystallization technique is available that allows controlled high
crystallization rate production of silicon wafers and advanced
metal-silicide alloys. Compared to other casting methods, such as e.g.
directional solidification, the RGS process allows better crystallization
control, high volume manufacturing and high material yield due to its
continuous, substrate-driven design. Insights from modelling the
characteristic melt flow in the casting frame are very desirable. To address
this demand, we are developing a new numerical tool based on OpenFOAM [1] which can
be utilized to simulate the free-surface dynamics of the melt flow under the
influence of alternating electromagnetic fields. The underlying
multi-physical model involves three-dimensional hydrodynamic and
magnetodynamic effects and their interaction.
