All previous models of grain-forming atmospheres have assumed that the mass flow is in a steady state. Such an assumption is not substantiated by observational data on late-type giants and, therefore, the usefulness of such models is quite limited. This study, however, assumes a time-dependent flow in an effort to model more closely the dynamic flows actually present in red giant atmospheres. To date, time-dependent models have been produced for two effective temperatures, Te = 2500 K and, Te = 2400 K.
