  A model for energy, pressure and flow velocity distributions at the beginning
of ultra-relativistic heavy ion collisions is presented, which can be used as
an initial condition for hydrodynamic calculations. Our model takes into
account baryon recoil for both target and projectile, arising from the
acceleration of partons in an effective field, produced in the collision. The
typical field strength (string tension) for RHIC energies is about 5-12 GeV/fm,
what allows us to talk about "string ropes". The results show that a QGP forms
a tilted disk, such that the direction of the largest pressure gradient stays
in the reaction plane, but deviates from both the beam and the usual transverse
flow directions. Such initial conditions may lead to the creation of "antiflow"
or "third flow component".
