If CYL or RCYL is defined, above coordinates will be
in cylindrical or reverse cylindrical coordinates system.
Optional coordinates x
o
, y
o
and z
o
will be the cartesian
coordinates for the origin of the cylindrical coordinates.
Defaults to 0, 0, 0 if not provided.
The 3 fields (x,y,z) may be replaced by a joint number
whose coordinates have been defined in the JOINT
COORDINATE command by entering
A

JOINT jn instead.

... =A rectangular super-element defined by four or eight
boundary points. There should be no spaces between
the letters.

of the super-
element. (Must not exceed 28).
n

A
k
of the super-
element. (Must not exceed 28).
If n
2
is omitted, that is, only n
1
is provided, then n
1
will indicate
the total number of elements within the super-element. In this case,
n
1
must be the square of an integer.
