• This paper presents a finite-difference solution of a crystal growth Stefanproblem in an isothermal binary component melt system. To ensure the accuracyof the computation without increasing the computational time, a variable schemeof grid size has been introduced whereby a smaller grid size is chosen at smalltimes when the effective number of grid points available for computations issmall. The numerical results are obtained for several values of the equilibriumparameter u. of the problem. The present results confirm that both the smalltime Lagrange-Bfirmann solution and the large time asymptotic solution of thesame problem given earlier by the author predict a correct behavior of the solutionover considerably extended physical time domains. An excellent experimentalverification is also obtained.
