The process of crystallization of silicon melt on a monotonically cooled disk located on the free surface of the melt is studied numerically. The influence of thermogravitational, thermal gravitational-capillary and mixed convection on the shape of the crystal-melt interface is investigated. In mixed convection modes, the speed of uniform rotation of the disk is set. The calculations were carried out in an axisymmetric formulation of problems by the finite element method using an adaptive triangular mesh and taking into account the latent heat.
