"""The AccelerationBaseMotionBC object stores the data for an acceleration base motion
boundary condition.
The AccelerationBaseMotionBC object is derived from the BoundaryCondition object.
Attributes
----------
name: str
A String specifying the boundary condition repository key.
amplitudeScaleFactor: float
A Float specifying the scale factor for the amplitude curve. The default value is 1.0.
useComplex: Boolean
A Boolean specifying whether to define the imaginary (out-of-plane) portion of the base
motion record given by amplitude definition. The default value is OFF.
centerOfRotation: tuple
A :py:class:`~abaqus.BasicGeometry.ModelDot.ModelDot` object specifying a tuple containing one center of rotation. The default
value is the global origin. This argument applies only when **dof=UR1**, UR2, or UR3.
correlation: CorrelationArray
A :py:class:`~abaqus.Amplitude.CorrelationArray.CorrelationArray` object.
secondaryBase: str
A String specifying the name of the :py:class:`~abaqus.BoundaryCondition.SecondaryBaseBC.SecondaryBaseBC` object associated with this boundary
condition. The default value is an empty string.
category: SymbolicConstant
A SymbolicConstant specifying the category of the boundary condition. Possible values
are MECHANICAL and THERMAL.
region: Region
A :py:class:`~abaqus.Region.Region.Region` object specifying the region to which the boundary condition is applied.
localCsys: str
None or a :py:class:`~abaqus.Datum.DatumCsys.DatumCsys` object specifying the local coordinate system of the boundary
condition's degrees of freedom. If **localCsys=None**, the degrees of freedom are defined
in the global coordinate system. The default value is None.

Parameters
----------
name
A String specifying the boundary condition repository key.
createStepName
A String specifying the name of the step in which the boundary condition is created.
dof
A SymbolicConstant specifying the constrained degree-of-freedom. Possible values for the
SymbolicConstant are U1, U2, U3, UR1, UR2, UR3. The default value is U1.
amplitudeScaleFactor
A Float specifying the scale factor for the amplitude curve. The default value is 1.0.
centerOfRotation
A ModelDot object specifying a tuple containing one center of rotation. The default
value is the global origin. This argument applies only when *dof*=UR1, UR2, or UR3.
correlation
A CorrelationArray object.
secondaryBase
A String specifying the name of the SecondaryBaseBC object associated with this boundary
condition. The default value is an empty string.
useComplex
A Boolean specifying whether to define the imaginary (out-of-plane) portion of the base
motion record given by amplitude definition. The default value is OFF.
amplitude
A String or the SymbolicConstant UNSET specifying the name of the amplitude reference.
UNSET should be used if the boundary condition has no amplitude reference. The default

specified step.
Returns
-------
