Abstract: We present a hydrodynamical model of the evolution of the circumstellar medium around a 60 MSolar star. Stars like this evolve from the main sequence, through the Luminous Blue Variable (LBV) phase to the Wolf-Rayet phase. An LBV star loses a large fraction of its mass in a short time through stellar wind. This mass loss event creates a circumstellar shell, which moves rapidly away from the star. A second shell is created when the star becomes a Wolf-Rayet star. This shell moves faster and will eventually collide with the first shell. Both shells are destroyed upon collision. Their remnants will continue to travel outward and will eventually dissipate into the surrounding medium.
