This input file is the one of the series of three
"sample-kits". It concerns the use of Fourier series to
generate the 2D BFC grids. It is wholly focused on
calculation of grid corner coordinates. Therefore, no
other actions are supported by input data.
It also differs from the previous examples in being
arranged as unsteady problem: at each time moment the
new BFC grid is PLANTed and dumped into specified file
to be viewed by PHOTON.

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 zig-zag channel of 2m width and 6pi
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.
