Attributes¶

model: Bastankhah2016Model

The model for computing common data

alpha: float

model parameter used to determine onset of far wake region, if not found in wake model

beta: float

model parameter used to determine onset of far wake region, if not found in wake model

wake_k: dict

Parameters for the WakeK class, if not found in wake model

induction: foxes.core.AxialInductionModel

The induction model, if not found in wake model
