Symmetry and symmetry conditions on boundaries
Symmetry
When a device has symmetry planes, it is possible to represent a fraction of the device, and to set appropriate symmetry conditions on the symmetry planes.
From a physical point of view, the symmetry boundary conditions are set on the state variable (potential).
| Symmetry condition | Anti-symmetry condition |

Example
Let's reconsider the preceding example.
The boundary conditions applied on the device boundaries are symmetry conditions (tangential field) on boundary 1 and anti-symmetry (normal field) on boundary 2.
