pysdic.IntegrationPoints.remove_points#

IntegrationPoints.remove_points(indices, inplace=False)[source]#

Remove specific integration points by their indices.

Parameters:

  • indices (ArrayLike) – The indices of the integration points to remove as a numpy ndarray with shape \((R,)\), where \(R\) is the number of points to remove.

  • inplace (bool, optional) – If True, modify the current instance in place, and return itself. If False, return a new IntegrationPoints instance (default is False).

Returns:

A new IntegrationPoints instance with the specified points removed or the modified current instance if inplace is True.

Return type:

IntegrationPoints

Raises:

IndexError – If any index is out of bounds.
