This paper shows the results of parallel experiments for the numerical simulation of the solidification of steel in continuous casting. The mathematical model is constituted by coupled non-linear boundary value problems. For the numerical solution of such partial differential equations we consider a semi-discretization with respect to the time of the studied evolution problem, while the spatial discretization is carried out by finite difference schemes. The large scale discretized algebraic systems are solved by sequential and parallel synchronous or asynchronous iterative relaxation algorithms. The comparison of these various previous methods are achieved when the thermal conductivity is constant.
