  The case considered is that of solid particles falling through
  stagnant liquid under gravity. A 1d unsteady simulation is
  performed with the algebraic slip model (asm), in which particles
  are released and allowed to fall under gravity. The particles
  eventually attain a uniform terminal settling velocity, under
  which the drag force balances the gravitational force. In the
  present case, the task is to calculate this velocity for which
  the theroretical value is 0.012m/s.

  The calculation may be performed in the x-, y- or z-direction with
  or without the liquid hydrostatic pressure included the solved-for
  pressure P1.
