This paper presents a level set method (LSM) for the analysis of a free surface largely deformed in the FZ method under microgravity. Three-dimensional numerical simulations are carried out to investigate the deformation processes of silicon liquid bridges with the coil position, width, and the magnitude of surface tension changed. The A-φ method is adopted to calculate the physical quantities of the alternating current magnetic field, and it is solved by the hybrid FEM-BEM. A liquid bridge becomes largely squeezed after 0.20s if its surface tension is set small. But the deformation becomes greatly suppressed if the surface tension is set large. Furthermore, it is found that the radius of a liquid bridge at the coil position varies when a coil is moved from the upper position in height to the middle one.
