This example Q1 demonstrates the use of 'Set internal
points of a blok' option for BFC-type grid. This option
is used to perform a three-dimensional interpolation
for the internal grid coordinates of a sub-domain; it
is used in three-dimensional cases when internal
points of a certain shape need smoothing; that
shape is then declared as a sub-domain over which
trans-finite or Laplace solver is used to perform
interpolation.
In this example 'Set internal points of a block'
option is used to distribute grid within a cube
that has been deformed by a half-cylinder.
*
Set the grid type to BFC
*

Enter cylinder diameter (default 0.5m)
Enter length of cube side (default 1.0m)

Input data used in this example:
*

-- Create half-cylinder --
Define points A,B,C and D
*
Draw two arc lines(AB & CD) and two straight
lines (BC & DA) to create a half-cylinder.
Lines AB&CD must have equal number of cells, as
well as lines BC&DA.

Enter number of cells for AB(&CD) lines (default 10)
Enter power distribution (for symmetric power-law
precede the number with S. (default 1.0)

Enter number of cells for BC(&DA) lines (default 10)
Enter power distribution (for symmetric power-law
precede the number with S. (default 1.0)
GSET(L,BC,B,C,nbc,pwr2)
Arc CD (C-D) goes through point
GSET(L,CD,C,D,nab,pwr1,ARC,side,
*
Define frame ABCD (half-cylinder) which has corner points
A,B,C,D
*
Enter number of cells for J direction (default 10)
Set the BFC grid dimension as nx x ny x nz cells with
cube dimensions (reference length) side x side x side.
*

Match grid plane J1 on frame ABCD using the
trans-finite method
*
Cube grid lines now pass through the cylinder. In
order to fit the grid to the new shape, the whole
domain is defined as 'sub-domain block' over which
Laplace solver is used to make internal grid
as orthogonal as possible.
