Details of a method for the numerical simulation of stellar pulsations and instabilities in the non-linear regime are presented. Important properties of the method are intrinsic mass and energy conservation. These are indispensable if the connection

The simulation of stellar instabilities requires a sufficient resolution of shocks, ionization zones and instability regions. Resolution problems in the latter may occur in simulations of the evolution of strange mode instabilities, if a Lagrangian d

Strange mode instabilities in the envelopes of massive stars lead to shock waves, which can oscillate on a much shorter timescale than that associated with the primary instability. The phenomenon is studied by direct numerical simulation using a, wit

The evolution of strange mode instabilities into the non linear regime has been followed by numerical simulation for an envelope model of a massive star having solar chemical composition, M=50M_sun, T_eff=10^4K and L=1.17*10^6 L_sun. Contrary to prev

If radiation pressure contributes significantly to the total pressure in models for the envelopes of hot and luminous stars, such as massive objects and Wolf—Rayet stars, strange—mode instabilities with growth rates in the dynamical range do occu

Known conservative remapping procedures in 2D computational fluid dynamics use the integral formulation of conservative laws and are very expensive because of volume integral calculations on overlapping grids. We suggest in the present paper a robust
