opensg.utils.shared.transform_beam_matrices(beam_stiff, beam_inertia)

Transform 6x6 beam stiffness and inertia matrices to a new reference frame.

Parameters:

beam_stiff (np.ndarray) – 6x6 stiffness matrix.
beam_inertia (np.ndarray) – 6x6 inertia matrix.

Returns:

beam_stiff_tr (np.ndarray) – Transformed 6x6 stiffness matrix.
beam_inertia_tr (np.ndarray) – Transformed 6x6 inertia matrix.
