&CELL: SOLIDS: CYLINDER


CENTRE

The location of the centre of gravity of the cylinder.

[No default.]


RADIUS

The radius of the cylinder.

[No default.]


HALF-LENGTH

Half the overall length of the cylinder, as measured along the central axis.

[No default.]


DIRECTION

The direction vector of the central axis of the cylinder.

The normalisation of the vector is not used. Zero-norm vectors are not acceptable.

[By default, the central axis is aligned with the z-axis.]


material

Specifies whether the cylinder is made of conducting or from dielectric material. To differentiate the solids in drawings, one has the option to choose between various representations:

Type Representation Notes
CONDUCTOR CONDUCTORS-1 Equivalent to CONDUCTOR-1
CONDUCTOR-1 CONDUCTORS-1 -
CONDUCTOR-2 CONDUCTORS-2 -
CONDUCTOR-3 CONDUCTORS-3 -
DIELECTRICUM DIELECTRICA-1 Equivalent to DIELECTRICUM-1
DIELECTRICUM-1 DIELECTRICA-1 -
DIELECTRICUM-2 DIELECTRICA-2 -
DIELECTRICUM-3 DIELECTRICA-3 -

[Default: CONDUCTOR]


label

A one character identification of the solid.

This label serves the same purpose as the wire label for wires, namely the selection of the solid as a place where signals can be measured, around which isochrons are drawn etc.

[Default: C]


N

The cylinder is drawn as a polygon with a finite number of panels. N specifies the number of panels on the cylinders outer wall.

N has only an optical effect. The algorithm which determines whether a point is inside or outside a cylinder, assumes a perfect cylinder, and does not take the value of N into account.

[By default, N is chosen in function of the size occupied by the cylinder in the drawing. If you decide to specify N manually, then the same number will be used no matter how large or small the cylinder appears in the drawing.]


ROTATE

Specifies a rotation angle of the cylinder in degrees.

Such a rotation is meaningful only if N has been chosen small.

Rotations have only an optical effect. The algorithm which determines whether a point is inside or outside a cylinder, assumes a perfect cylinder and thus does not take rotations into account.

[Default: 0 degrees]
