Steady state temperature field in a co-ordinate system attached to the mould has been considered. Phase change is assumed to take place at constant temperature. The nonlinearity in this problem is caused by the unknown location of the solid liquid interface. To determine both this location md the temperature field in the ingot an original BEM technique has been developed. C' smooth quadratic elements has been used to interpolation of phase change interface. Finally, the interface has been approximated by Bezier cubic splmes to decrease the number degrees of freedom of this interface. A numerical example is i
