Attributes
----------
name: str
A String specifying the boundary condition repository key.
distributionType: SymbolicConstant
A SymbolicConstant specifying how the boundary condition is distributed spatially.
Possible values are UNIFORM, USER_DEFINED, and FIELD. The default value is UNIFORM.
fieldName: str
A String specifying the name of the :py:class:`~abaqus.Field.AnalyticalField.AnalyticalField` object associated with this boundary
condition. The **fieldName** argument applies only when **distributionType=FIELD**. 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.

Possible values for the SymbolicConstant are UNSET and SET. The default value is
UNSET.Note:Although *v1*, *v2*, *v3*, *vr1*, *vr2*, and *vr3* are optional arguments, at
least one of them must be specified.
v2
A Float or a SymbolicConstant specifying the velocity component in the 2-direction.
Possible values for the SymbolicConstant are UNSET and SET. The default value is UNSET.
v3
A Float or a SymbolicConstant specifying the velocity component in the 3-direction.

vr1
A Float or a SymbolicConstant specifying the rotational velocity component about the
1-direction. Possible values for the SymbolicConstant are UNSET and SET. The default
value is UNSET.

2-direction. Possible values for the SymbolicConstant are UNSET and SET. The default
value is UNSET.
vr3
A Float or a SymbolicConstant specifying the rotational velocity component about the
3-direction. Possible values for the SymbolicConstant are UNSET and SET. The default
value is UNSET.
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
value is UNSET. You should provide the *amplitude* argument only if it is valid for the
specified step.
localCsys
None or a 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.
distributionType
