pysdic.Connectivity.concatenate

Connectivity.concatenate(other, inplace=False)

Concatenate the current connectivity with another Connectivity instance.

This method combines the elements from both connectivities into a new Connectivity object.

Note

The properties in common between the two connectivities are also concatenated. If a property exists in only one of the connectivities, it will be filled with numpy.nan values for the points from the other connectivity.

Parameters:

• other (Connectivity) – Another Connectivity instance to concatenate with the current connectivity.

• inplace (bool, optional) – If True, modifies the current connectivity in place and returns itself. If False, returns a new Connectivity instance (default is False).

Returns:

A new Connectivity object containing the concatenated elements from both connectivities or the modified current instance if inplace is True

Return type:

Connectivity

Raises:

ValueError – If the input is not an instance of Connectivity. If the two connectivities have different dimensions.

Examples

Creating two Connectivity objects.

import numpy as np
from pysdic import Connectivity

# Create two random NumPy arrays of shape (100, 3)
random_elements1 = np.random.randint(0, 100, size=(100, 4))  # shape (100, 4)
random_elements2 = np.random.randint(0, 100, size=(50, 4))   # shape (50, 4)

connectivity1 = Connectivity.from_array(random_elements1)
connectivity2 = Connectivity.from_array(random_elements2)

Concatenate the two connectivities using the concatenate() method.

# Concatenate the two connectivities
concatenated_connectivity = connectivity1.concatenate(connectivity2)

print(concatenated_connectivity.elements)
# Output: A NumPy array of shape (150, 4) containing the concatenated elements
