An estimate of the effects of convection on the limiting amplitude behavior of RR Lyrae stars has been obtained by direct integration of a convective nonlinear model to limiting amplitude. A detailed analysis of the approach to the limit is made, over a 100 period interval. The presence of convection significantly lowers the final amplitude when compared with fully radiative models, but the actual amplitude obtained is sensitive to the form of the eddy viscosity. Artificial viscosity plays no role in this case, in sharp contrast to previous large-amplitude radiative models. An analysis of the stability of the limit cycle is presented, using a new analysis technique.
