flow360.WallRotation

class WallRotation

Bases: Flow360BaseModel

WallRotation class to specify the rotational velocity model for the Wall boundary condition.

The wall rotation model prescribes a rotational motion at the wall by defining a center of rotation, an axis about which the wall rotates, and an angular velocity. This model can be used to simulate rotating components or surfaces in a flow simulation.

Example

>>> fl.Wall(
...     entities=volume_mesh["fluid/wall"],
...     velocity=fl.WallRotation(
...         axis=(0, 0, 1),
...         center=(1, 2, 3) * u.m,
...         angular_velocity=100 * u.rpm
...     ),
...     use_wall_function=True,
... )
