    This input  file  is  the  one  of  the  series of three
    "sample-kits". It concerns the generation of four 3D BFC
    grids  to  be  fitted  with:  corrugated  circular pipe,
    helically coiled pipe,  snail-like chamber  and  "igloo"
    object.

    The problem  is  wholly  focused  on calculation of grid
    corner coordinates.  Therefore,  no other functions  are
    supported by input data.

    It is arranged as unsteady problem:  at each time moment
    the new BFC grid is PLANTed and  dumped  into  specified
    file to be viewed by PHOTON.

       1.   3D corrugated circular pipe
            ---------------------------

REAL(LENGTH,TWOPI,LITTLER)

    ZC=:LENGTH:*FLOAT(K-1)/FLOAT(NZ)
  IF(ISTEP.EQ.1.AND.ISWEEP.EQ.1)
    The above   three   statements  contain  rather  lengthy
    algebraic  formulae.  All  together  they  provide   the
    calculation of cartesian coordinates for cell corners of
    the grid fitted  the  corrugated  circular  pipe  of  1m
    diameter and 10m length,  as can be seen by PHOTON.  The
    grid is uniform in both  direction.  The  generation  is
    made at the first sweep of the first time step.

  IF(ISTEP.EQ.2.AND.ISWEEP.EQ.1)
    The above three  statements  perform  the  corresponding
    functions  for the generation of the uniform grid fitted
    the helically coiled pipe of 0.25 m diameter. It is made
    at the first sweep of the second time step.

  IF(ISTEP.EQ.3.AND.ISWEEP.EQ.1)
    At the first sweep of the third time step the generation
    of  the  snail-like  chamber  is  made governed by above
    formulae.

  IF(ISTEP.EQ.4.AND.ISWEEP.EQ.1)
    At the   first   sweep  of  the  fourth  time  step  the
    generation of the  last  grid  of  the  series  is  made
    governed by above formulae.
