flow360.Periodic

class Periodic

Bases: Flow360BaseModel

Periodic defines the translational or rotational periodic boundary condition.

Example

• Define a translationally periodic boundary condition using Translational:

  >>> fl.Periodic(
  ...     surface_pairs=[
  ...         (volume_mesh["VOLUME/BOTTOM"], volume_mesh["VOLUME/TOP"]),
  ...         (volume_mesh["VOLUME/RIGHT"], volume_mesh["VOLUME/LEFT"]),
  ...     ],
  ...     spec=fl.Translational(),
  ... )
  

• Define a rotationally periodic boundary condition using Rotational:

  >>> fl.Periodic(
  ...     surface_pairs=[(volume_mesh["VOLUME/PERIODIC-1"],
  ...         volume_mesh["VOLUME/PERIODIC-2"])],
  ...     spec=fl.Rotational()
  ... )
