Abstract The usefulness of low gravity for growing homogeneous, exceptionally pure crystals has been demonstrated several times in the past. Crystals of both organic and inorganic substances have been successfully grown in space, obtaining a purity and homogeneity unachievable in 1-g conditions. In this paper, a numerical modelling was performed to simulate the free surface behaviour and the solid/liquid interface shape for a germanium float zone. In order to verify the accuracy of the programme, a comparison between numerical and experimental results for a sodium nitrate liquid column was made.
