We have studied the relativistic beamed outflow proposed to occur in the collapsar model of gamma-ray bursts. A jet forms as a consequence of an assumed energy deposition of 10⁵⁰- 10⁵¹ erg/s within a 30∘ cone around the rotation axis of the progenitor star. The generated jet flow is strongly beamed (few degrees) and reaches the surface of the stellar progenitor (r ≈ 3 10¹⁰ cm) intact. At break-out the maximum Lorentz factor of the jet flow is about 33. Simulations have been performed with the GENESIS multi-dimensional relativistic hydrodynamic code.
