Attributes¶

model: Bastankhah2016Model

The model for computing common data

model_pars: dict

Model parameters

K: float

The wake growth parameter k. If not given here it will be searched in the farm data.

YAWM: float

The yaw misalignment YAWM. If not given here it will be searched in the farm data.

base_frame: foxes.core.WakeFrame

The wake frame from which to start

k_var: str

The variable name for k
