Abstract: In this paper, a new solution of solidification problems in continuous casting based on meshless method is presented with multiple strategies to solve the practical problems. An additional term is added to stabilise the computation with Neumann boundary. The enthalpy method is used to calculate the latent heat and the corresponding iterative solution is given. An iteration scheme for non-linear material calculation is also constructed. The model is verified by a 2D FEM solidification example. Finally, it is applied to the simulation of the solid shell growth in the continuous bloom and billet casting moulds. The result is coincided with the measurement.

Keywords: meshless methods; finite point method; FPM; solidification; Stefan problem; continuous casting; simulation; solid shell growth.
