How to change the grid point coordinates at which the flow field velocity will be recorded using the FlorisInterface?

I would like to change the grid point coordinates at which I calculate the wake so I can properly compare it to CFD simulations.

Currently, I am using the FLORIS framework with FlorisInterface. It seems that I could either choose to define the points in calculate_wake(points=...) or by defining the resolution (with_resolution=Vec3) and x,y,z-bounds (bounds_to_set=...) when reinitializing the flow field with reinitialize_flow_field(...).

There are problems I come across:

  1. when using FlorisInterface it seems that it cannot find the parameter bounds_to_set in reinitialize_flow_field(...), however it is present in simulation.flow_field.
  2. I have trouble figuring out how points=... needs to be formatted in calculate_wake(points=...); the documentation says it is an array containing x-, y-, and z-coordinates, but I am not sure how the array should be shaped.

What is generally the most appropriate way to define user-specified grid points in the set-up?

have you looked at the example:

examples/flow_interaction/get_points_from_flow.py

This shows how to select arbitrary points from 1D x,y,z arrays:

# Define a set points running through one row
x_points = np.arange(-100, 1000, 1)
y_points = np.zeros_like(x_points)
z_points = np.ones_like(x_points) * 100

# Get the values
flow_points = fi.get_set_of_points(x_points, y_points, z_points)

print(flow_points)
