This example Q1 demonstrates the use of Copy-Rotate
option for BFC-type grid; it is used here to create
S-bend of a tube.

*
Set the grid type to BFC

Input data used in this example:

*
Define points A,B,C and D
Point A positioned at (0,0,0)
GSET(P,A,0,0,0)
*
Draw  four arc lines (AB,BC,CD,DA) from A to D
to create a circle.
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)
Arc AB (A-B) goes through point (0,radius-root,root)

Enter number of cells for BC(&DA) lines (default 5)
Arc BC (B-C) goes through point (0,radius+root,root)
Arc CD (C-D) goes through point (0,radius+root,-root)
Arc DA (D-A) goes through point (0,radius-root,-root)
*
Define frame ABCD (circle) which has corner points
A,B,C,D
*
Enter number of cells for I direction (default 20)
*

Match grid plane I1 on frame ABCD using the
trans-finite method
*
Enter shifting distance; it will define a straight part
Copy planes with a distance (dx=shift,dy=0,dz=0), including
internal planes; internal planes are uniformly distributed,
hence power is set to 1.
*
Z axis located at X=shift, Y=-0.2 m, clock-wise by 90deg.(PI/2)
Include internal planes and distribute them uniformly.
*
Z axis located at X(axis)=shift+radius*2+0.4, Y=-0.2 m, anti-
clock-wise by 90deg.(PI/2). Include internal planes and
distribute them uniformly.
*
shifting it with a distance (shift,0,0), including internal
planes, uniformly distributed.
