     This example Q1 demonstrates the use line-curve
     option for BFC-type grid. This option is used to
     create a spline curve between two end-points through
     the user-set points, and with the user-set starting
     end ending curvature.
     In this example, line-curvature is used to create
     car-body-like profile which is then copied to
     create simplified car body.

  *
     Set the grid type to BFC
  *

     Enter the overall length of the car (default 3.85m)
     Characteristic length(CL) is calculated as length/55
     Input data used in this example:

  *

      -- Create a car profile --
     Define points A,B,C and D
     Point A positioned at (0,0,0)
       GSET(P,A,0,0,0)
     Point B positioned at (0,1.05,0.84)
       GSET(P,B,0,cl*15,cl*12)
     Point C positioned at (0,1.96,1.4)
       GSET(P,C,0,cl*28,cl*20)
     Point D positioned at (0,3.85,0)
  *
     Draw four curves (AB,BC,CD,DA) from A to D
     to create a car-profile.
     Lines AB&CD must have equal number of cells, as
     well as lines BC&DA. Power is set to 1.0, ie. cells
     are uniformly distributed.

     Enter number of cells for AB(&CD) lines (default 5)

     Start a spline curve C1 at point A.
       GSET(V,C1,S,A,SPLINE)
     Start with a zero-curvature; ie. allow program
     to fit curve between points and decide curvature.
           GSET(V,0,0,0)
    GSET(V,0,0,0)
     Define point on a curve (0,0.07,0.35)
       GSET(V,0,cl*1,cl*5)
     Define point on a curve (0,0.21,0.63)
       GSET(V,0,cl*3,cl*9)
     End spline curve at point B.
       GSET(V,C1,E,B)
     uniformly distributed cells, using curve C1.


     Enter number of cells for BC(&DA) lines (default 5)
     Start a spline curve C2 at point B.
       GSET(V,C2,S,B,SPLINE)
     Define point on a curve (0,1.33,1.12)
       GSET(V,0,cl*19,cl*16)
     Define point on a curve (0,1.61,1.3)
       GSET(V,0,cl*23,cl*18.5))
     End spline curve at point C.
     GSET(V,C2,E,C)
     uniformly distributed cells, using curve C2.

     Start a spline curve C3 at point C.
       GSET(V,C3,S,C,SPLINE)
     Define point on a curve (0,2.66,1.3)
       GSET(V,0,cl*38,cl*18.5)
     Define point on a curve (0,3.29,0.98)
       GSET(V,0,cl*47,cl*14)
     Define point on a curve (0,3.64,0.63)
       GSET(V,0,cl*52,cl*9)
     Define point on a curve (0,3.78,0.35)
       GSET(V,0,cl*54,cl*5)
     End spline curve at point D.
       GSET(V,C3,E,D)
     uniformly distributed cells, using curve C3.

     uniformly distributed cells.
       GSET(L,DA,D,A,nbc,1.0)
     Define frame ABCD (car profile) which has corner points
     A,B,C,D
  *

     Enter number of cells in I (car-width) direction (def. 10)
     Set the BFC grid dimension as nx x nbc x nab cells with
     reference length width x length x height.
  *

     Match grid plane I1 on frame ABCD using the
     trans-finite interpolation method
  *
     with a distance (dx=width,dy=0,dz=0), including internal
     planes;internal planes are uniformly distributed, hence
     power is set to 1.
