class elastica.rigidbody.rigid_body.RigidBodyBase

Base class for rigid body classes.

Notes

All rigid body class should inherit this base class.

compute_internal_forces_and_torques(time)

For rigid body, there is no internal forces and torques

Return type:

None

compute_position_center_of_mass()

Return positional center of mass

Return type:

ndarray[Any, dtype[float64]]

compute_translational_energy()

Return translational energy

Return type:

ndarray[Any, dtype[float64]]

compute_rotational_energy()

Return rotational energy

Return type:

ndarray[Any, dtype[float64]]
