morph_drain

morph_drain(image, target_saturation=0.1, delta_r=0.05, initial_radius=9999)

Compute the morphological drainage curve to the target saturation.

Return type:

Tuple[ndarray, ndarray, ndarray]

Parameters:

• image – A binary image where the pore phase is labeled 1 and the grain phase is labeled 0.

• target_saturation – The target saturation for the morphological drainage curve. Default = 0.1

• delta_r – Factor by which the invasion radius is decreased. Default = 0.05

• initial_radius – Initial guess for the invasion radius. Default = min(initial_radius, maximum Euclidean distance)

Returns:

The invasion radii and their respective wetting saturation. 3D image of the estimated fluid configurations at the target saturation.

Return type:

Tuple[numpy.ndarray, numpy.ndarray, np.ndarray]
