Abstract: We show effects of granular structure of the initial conditions IC ofhydrodynamic description of high-energy nucleus-nucleus collisions on someobservables, especially on the elliptic-flow parameter v2. Such a structureenhances production of isotropically distributed high-pT particles, making v2smaller there. Also, it reduces v2 in the forward and backward regions wherethe global matter density is smaller, so where such effects become moreefficacious.
