Summary
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 nonlinear boundary value problems. For the numerical solution of
such partial differential equations we consider a semidiscretization 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.
