get_receiver
(grid, values, coordinates, method='cubic', extrapolate=False)[source]¶ Return values corresponding to grid at coordinates.
Works for electric fields as well as magnetic fields obtained with
get_h_field()
, and for model parameters.Parameters: - grid :
emg3d.meshes.TensorMesh
The model grid.
- values : ndarray
Field instance, or a particular field (e.g. field.fx); Model parameters.
- coordinates : tuple (x, y, z)
Coordinates (x, y, z) where to interpolate values; e.g. receiver locations.
- method : str, optional
The method of interpolation to perform, ‘linear’ or ‘cubic’. Default is ‘cubic’ (forced to ‘linear’ if there are less than 3 points in any direction).
- extrapolate : bool
If True, points on new_grid which are outside of grid are filled by the nearest value (if
method='cubic'
) or by extrapolation (ifmethod='linear'
). If False, points outside are set to zero.Default is False.
Returns: - new_values : ndarray or
utils.EMArray
Values at coordinates.
If input was a field it returns an EMArray, which is a subclassed ndarray with
.pha
and.amp
attributes.If input was an entire Field instance, output is a tuple (fx, fy, fz).
