  The depth of the convective envelope plays a fundamental role in the driving
mechanism proposed by Guzik et al. (2000) to explain the high-order g modes of
gamma Dor pulsators. In this poster we study the sensitivity of the convective
envelope depth to the description of convective transport, to relevant physical
processes, such as microscopic diffusion, and to other uncertainties in
theoretical stellar models.
