Quite straightforward question. We can change some properties of turbine with fi.reinitialize_flow_field. You may also set the wake model directly on the script with (according to what I understood from the docs):
floris.farm.set_wake_model('curl')
So, is there any similar method to perform the same for the tuning wake parameters? I mean, change their values directly on script without having to go through the input file and change manually.
Yes, there are methods to get and set the wake model parameters programatically, without having to edit the input file directly. An example is provided in the latest FLORIS version under floris/examples/_getting_started/example_03_get_and_set_model_parameters.py. A dictionary of parameters for the currently set model can be obtained through the FLORIS interface object by using:
import floris.tools as wfct
# Initialize the FLORIS interface fi
fi = wfct.floris_interface.FlorisInterface("../example_input.json")
# Get the current model parameters
model_params = fi.get_model_parameters()
This dictionary can be modified and fed back to the FLORIS interface object by using:
fi.set_model_parameters(model_params)
If you simply want to view the current model parameters, you can use the method:
fi.show_model_parameters()
Please see the example for further details on the functionality available to explore the model parameters.
