Abstract: Numerical simulations of the evolution of strange-mode instabilities into the non-linear regime have been performed for a wide range of stellar parameters for Wolf-Rayet stars. It has been shown that the Wolf-Rayet models reach radial velocities which amount to up to 30% of their escape velocity. The acoustic luminosities suggest a connection to the observed mass loss. Most of the models show a jump in the mean effective temperature after reaching the non-linear regime. This jump is related to the run of the opacity.
