Query: Nonlinear Pulsations of Convective Stellar Models   We review the numerical modelling of the nonlinear pulsations of classical
variable stars with hydrocodes that include the effects of turbulent
convection. Despite their simplicity these turbulent convective recipes appear
to remove many of the difficulties that radiative codes faced. In particular,
the numerical modelling of double mode pulsations has become possible.
