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)
LENGTH=10.0
LITTLER=1.0;TWOPI=2.0*3.14157
XC=ABS(COS(:LENGTH:*FLOAT(K-1)/FLOAT(NZ)))+$
:LITTLER:*FLOAT(J-1)/FLOAT(NY)* C$
OS(:TWOPI:*FLOAT(I-1)/FLOAT(NX))
YC=ABS(COS(:LENGTH:*FLOAT(K-1)/FLOAT(NZ)))+$
:LITTLER:*FLOAT(J-1)/FLOAT(NY)* S$
IN(:TWOPI:*FLOAT(I-1)/FLOAT(NX))
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.

2. 3D helically coiled pipe
-------------------------
REAL(LITLER)
LITLER=0.25
XC=:LITLER:*FLOAT(J-1)/FLOAT(NY)* COS(:TWOPI:$
*FLOAT(I-1)/FLOAT(NX))+ COS(4.75*6.28314*FLOAT(K-1)/FLOAT(NZ$

*FLOAT(I-1)/FLOAT(NX))+ SIN(4.75*6.2831*FLOAT(K-1)/FLOAT(NZ$
))
ZC= 5.5*FLOAT(K-1)/FLOAT(NZ)
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.

3. 3D snail-like chamber
---------------------
REAL(LITR)
LITR=1.0
RG(1)=TWOPI
XC=:LITR:*FLOAT(J-1)/FLOAT(NY)* (COS(RG(1)*FL$
OAT(I-1)/FLOAT(NX))+ RG(1)*FLOAT(I-1)/FLOAT(NX)*$
SIN(RG(1)*FLOAT(I-1)/FLOAT(NX)))
YC=:LITR:*FLOAT(J-1)/FLOAT(NY)* (SIN(RG(1)*FL$
OAT(I-1)/FLOAT(NX))- RG(1)*FLOAT(I-1)/FLOAT(NX)*$
COS(RG(1)*FLOAT(I-1)/FLOAT(NX)))
ZC=10.*FLOAT(K-1)/FLOAT(NZ)
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.

4. 3D igloo

XC=:LITR:*FLOAT(J-1)/FLOAT(NY)* COS(:TWOPI:*$
FLOAT(I-1)/FLOAT(NX))
YC=:LITR:*FLOAT(J-1)/FLOAT(NY)* SIN(:TWOPI:*$
FLOAT(I-1)/FLOAT(NX))
ZC=:LITR:*FLOAT(K-1)/FLOAT(NZ)*$
0.5*(SIN(:TWOPI:* FLOAT(J-1)/FLOAT(NY))+1)
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.
