At laboratory scales model experiments are an often used approach to industrial processes such as the Czochralski crystal growth method. Due to the availability of suitable measuring techniques, the low melting alloy GaInSn, which is liquid at room temperature became meanwhile as de facto standard.

The Ribbon Growth on Substrate (RGS) technology is a crystallization technique that allows direct and efficient casting of silicon wafers and sheets of advanced metal-silicide compounds. A reasonable level of stability and controllability of this process can howe­ver only be achieved with the help of tailored AC magnetic fields. In order to design theses fields and to understand their complex interaction with the melt flow, specialized numerical tools are required.
