Query: Analyses of collective flow and space-time evolution based on
  relativistic hydrodynamical model   We numerically solve fully (3+1)-dimensional relativistic hydrodynamical
equation with the baryon number conservation law. For realistic initial
conditions we adopt the results from the event generator (URASiMA). Using this
model we discuss collective flow.
