Members of the team sucesfully completed hydrodynamical code for time dependent models of multicomponent stellar winds. With this code we analysed stability of various models of radiatively driven stellar winds from hot stars. But these models were simplified due to the expression of radiative force, which is right only in Sobolev approximation. For consistent review of stability and for analyse of instabilities generated in the radiatively driven stellar winds we must include in radiative force non-local radiative processes. The aim of the proposed project is extension of the code for more detail calculation of radiative force . Moreover, instead of isothermal processes we plan to use energy balance equation with radiative cooling and heating term.
