- Reflection
Select a Number of reflection symmetries, and select a reference z-symmetry value (axisymmetric models), a symmetry axis (two-dimensional models), or a symmetry plane (three-dimensional models) for each reflection.
Abaqus/CAE adds the reflected surfaces to the cavity definition and reduces the remaining number of symmetries allowed in the model. Toggle on Highlight to view the current parameter selections in the viewport.
- Periodic
Select a Number of periodic symmetries and number of repetitions for each periodic symmetry. For axisymmetric models, select a reference z-symmetry value and a periodic z-distance value. For two-dimensional and three-dimensional models, select a symmetry axis and a distance vector or a symmetry plane and a distance vector, respectively, for each periodic symmetry.
Abaqus/CAE adds the periodic surfaces to the cavity surfaces you selected for the Properties options and reduces the remaining number of symmetries allowed in the model. Toggle on Highlight to view the current parameter selections in the viewport.
- Cyclic
Toggle on Use cyclic symmetric and select the total number of sectors. Select the symmetry point and a point on the axis of symmetry (two-dimensional models) or the first and second points on the axis of symmetry and a point on the symmetry plane (three-dimensional models).
Cyclic symmetry creates new sectors by rotating the original geometry clockwise about the axis of symmetry. Cyclic symmetry is not available for axisymmetric models.
The following conditions must be met:
For two-dimensional models the selected point on the axis of symmetry must be on the clockwise side of the geometry defining the original sector.
For three-dimensional models the selected point on the symmetry plane must be on the counterclockwise side of the geometry defining the original sector.
The total number of sectors must define a complete circle (360°). If you change the number of sectors, you must redefine the geometry to represent the correct portion of the model.
