    ----------
    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.

        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.
        region
            A :py:class:`~abaqus.Region.Region.Region` object specifying the region to which the boundary condition is applied.
        fieldName
            A String specifying the name of the AnalyticalField object associated with this boundary
            condition. The **fieldName** argument applies only when **distributionType** = FIELD. The
            default value is an empty string.
        magnitude
            A Float specifying the temperature magnitude. The default value is 0.
        dof
            A sequence of Ints specifying the degrees of freedom to which the boundary condition is
            applied. The default value is (11,).
        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.
        distributionType
            A SymbolicConstant specifying how the boundary condition is distributed spatially.
            Possible values are UNIFORM, USER_DEFINED, and FIELD. The default value is UNIFORM.
        fixed
            A Boolean specifying whether the boundary condition should remain fixed at the current
            values at the start of the step. The default value is OFF.
