class DisplacementBaseMotionBCState(BoundaryConditionState):
    """The DisplacementBaseMotionBCState object stores the propagating data for a velocity base
    motion boundary condition in a step. One instance of this object is created internally 
    by the DisplacementBaseMotionBC object for each step. The instance is also deleted 
    internally by the DisplacementBaseMotionBC object. 
    The DisplacementBaseMotionBCState object has no constructor or methods. 
    The DisplacementBaseMotionBCState object is derived from the BoundaryConditionState 
    object. 

    Attributes
    ----------
    amplitudeState: SymbolicConstant
        A SymbolicConstant specifying the propagation state of the amplitude reference. Possible
        values are UNSET, SET, UNCHANGED, FREED, and MODIFIED.
    status: SymbolicConstant
        A SymbolicConstant specifying the propagation state of the :py:class:`~abaqus.BoundaryCondition.BoundaryConditionState.BoundaryConditionState` object. Possible values are:
        NOT_YET_ACTIVE
        CREATED
        PROPAGATED
        MODIFIED
        DEACTIVATED
        NO_LONGER_ACTIVE
        TYPE_NOT_APPLICABLE
        INSTANCE_NOT_APPLICABLE
        PROPAGATED_FROM_BASE_STATE
        MODIFIED_FROM_BASE_STATE
        DEACTIVATED_FROM_BASE_STATE
        BUILT_INTO_MODES
    amplitude: str
        A String specifying the name of the amplitude reference. The String is empty if the
        boundary condition has no amplitude reference.
