flow360.ReferenceFrameExpression

class ReferenceFrameExpression

Bases: ReferenceFrameBase

ReferenceFrameExpression class for setting up reference frame using expression

Parameters:

• model_type (Literal['Expression'] = Expression) – center : _VectorType axis : Vector parent_volume_name : Optional[str] = None theta_radians : Optional[str] = None theta_degrees : Optional[str] = None

• center (Coordinate) – Coordinate representing the origin of rotation, eg. (0, 0, 0)

• axis (Axis) – Axis of rotation, eg. (0, 0, 1)

• parent_volume_name (str, optional) – Name of the volume zone that the rotating reference frame is contained in, used to compute the acceleration in the nested rotating reference frame

• theta_radians (str, optional) – Expression for rotation angle (in radians) as a function of time

• theta_degrees (str, optional) – Expression for rotation angle (in degrees) as a function of time

Returns:

An instance of the component class ReferenceFrame.

Return type:

ReferenceFrameExpression

Example

>>> rf = ReferenceFrameExpression(
        center=(0, 0, 0),
        axis=(0, 0, 1),
        theta_radians="1 * t"
    )
