Symmetry: definition (structure)
Definition
The Symmetry entity is defined by:
- a name
- a type of symmetry
- position of symmetry axes or planes
Name
The name to identify the symmetry is allocated automatically by Flux during the creation of this one.
The user cannot modify this name.
Types of symmetries: 2D domain
The symmetry types and the characteristics useful for their description are gathered in the table below.
| Symmetry axis | Offset position |
|---|---|
| versus X-axis | X |
| versus Y-axis | Y |
| Symmetry axis | Offset angle |
|---|---|
| defined by an offset angle about Z | with respect to the X-axis |
Types of symmetries: 3D domain
The symmetry types and the characteristics useful for their description are gathered in the table below.
| Symmetry plane | Offset position |
|---|---|
| versus XY plane | Z |
| versus YZ plane | X |
| versus ZX plane | Y |
| Symmetry plane | Offset angle |
|---|---|
| defined by an offset angle about X-axis | with respect to the XY plane |
| defined by an offset angle about Y-axis | with respect to the YZ plane |
| defined by an offset angle about Z-axis | with respect to the ZX plane |
Important
It is not possible to change the type of the symmetryby editing its dialog box.
To change the symmetry type:
- Delete the symmetry
- Create a new symmetry
Length and angle units
Length and angle units are those associated with the domain.
These units can be edited and modified in the dialog box of the Domain Type.
