Abstract: The paper presents the results of a comparison of two ap-proaches to calculation of the time dependence of the relative concentration of a cellular substance obtained when describing the initial stage of formation of nanowires in areas of selective etching. It is shown that for moderate values of the initial con-centration of a substance on a substrate, the cellular automaton model reproduces fairly accurately the results obtained using the classical finite-difference scheme of numerical solution of the equation describing the considered physical process. It is shown that this model makes it possible to go beyond the clas-sical description and obtain similar results for cases of ultra-low or ultra-high initial concentration values.
