## 6.4. Profile Transformation

The `Profile Transformation` method:

- Is available when there is at least one interface that uses the `Transient Rotor Stator` frame change/mixing model.

- Applies to any domain interface using the `Transient Rotor Stator` frame change/mixing model that is not used in the Time Transformation or Fourier Transformation model.

- Uses conventional periodicity at periodic boundaries (that is, has no special time lag for phase shift treatment).

- Results in the same solution as a transient simulation that uses the `Transient Rotor Stator` frame change/mixing model with the same time step specifications.

Note: See Profile Transformation in the CFX-Solver Theory Guide for more theoretical information about the Profile Transformation method.
