to_indices

FaceCenteredCubic.to_indices(mask)

Converts a boolean mask to pore or throat indices

Parameters:

mask (ndarray) – A boolean mask with True values indicating either pore or throat indices. This array must either be Nt or Np long, otherwise an Exception is raised.

Returns:

indices – An array containing numerical indices of where mask was True.

Return type:

ndarray

Notes

This function is equivalent to just calling np.where(mask)[0] but does check to ensure that mask is a valid length.
