    ----------
    name: str
        A String specifying the load repository key.
    distributionType: SymbolicConstant
        A SymbolicConstant specifying whether the load is uniform. Possible values are UNIFORM,
        HYDROSTATIC, USER_DEFINED, and FIELD. The default value is UNIFORM.
    side: SymbolicConstant
        A SymbolicConstant specifying whether the pressure is applied internally or externally.
        Possible values are INTERNAL and EXTERNAL. The default value is INTERNAL.
    diameter: float
        A Float specifying the effective inner or outer diameter.
    field: str
        A String specifying the name of the :py:class:`~abaqus.Field.AnalyticalField.AnalyticalField` object associated with this load.

            A Region object specifying the region to which the load is applied.
        magnitude
            A Float specifying the pressure magnitude.Note:*magnitude* is optional if
            *distributionType*=USER_DEFINED.
        diameter
            A Float specifying the effective inner or outer diameter.
        hZero
            A Float specifying the height of the zero pressure level when
