- A symmetric transform - if a boundary is of type symmetry, then a corresponding symmetry transform node is created and stored under the Tools > Transforms node, its name being that of the boundary.
- A periodic transform - if there is a periodic interface in the simulation, then a corresponding periodic transform node is created and stored under the Tools > Transforms node, its name being that of the interface.
- The identity transform - this is the default transform, and lives under the Tools > Transforms node.
