All user-defined transforms can be deleted by right-clicking on the transform node and selecting Delete. Automatically created transforms are managed by the simulation, and will only be deleted when deemed necessary by the simulation. For example, a periodic transform is tied to an interface and will be deleted if the interface is deleted or the interface type is changed from periodic. Similarly, a symmetry transform is tied to a symmetry boundary and will be deleted if the boundary is deleted or the boundary type changes. An identity transform cannot be deleted.
