This option is used to define cavity symmetry by cyclic repetition about a point or an axis. The *CYCLIC option can be used only following the *RADIATION SYMMETRY option.
Product: ABAQUS/Standard
Type: History data
Level: Step
Set this parameter equal to the number of cyclically similar images that compose the cavity formed as a result of this symmetry. The angle of rotation (about a point or an axis) used to create cyclically similar images is equal to 360°/NC.
Set TYPE=POINT to create a two-dimensional cavity by cyclic repetition of the cavity surface defined in the model by rotation about a point, 
. See Figure 3.78–1. The cavity surface defined in the model must be bounded by the line 
and a line passing through at an angle, measured counterclockwise when looking into the plane of the model, of 360°/NC to .
Set TYPE=AXIS to create a three-dimensional cavity by cyclic repetition of the cavity surface defined in the model by rotation about an axis, 
. See Figure 3.78–2. The cavity surface defined in the model must be bounded by the plane 
and a plane passing through line at an angle, measured clockwise when looking from to 
, of 360°/NC to . Line must be normal to line .
