Use the Rotating Frame node to add a rotating frame contribution to the Hamiltonian.

From the Axis of rotation list, select x-axis, y-axis, z-axis (default), or User defined. For user defined, enter the Rotation axis base point (SI unit: m, default: the origin) and the Rotation axis direction (dimensionless, default: +z direction).

The axis of rotation is fixed in the out-of-plane direction. Enter the Rotation axis base point (SI unit: m, default: the origin).

Enter the Rotation speed in the text field (SI unit: rad/s, default: 0).
