Attributes
----------
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.
The **field** argument applies only when **distributionType=FIELD**. The default value is an
empty string.
region: Region
A :py:class:`~abaqus.Region.Region.Region` object specifying the region to which the load is applied.

Parameters
----------
name
A String specifying the load repository key.
createStepName
A String specifying the name of the step in which the pressure is created.
region
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
*distributionType*=HYDROSTATIC.
hReference
A Float specifying the height of the reference pressure level when
*distributionType*=HYDROSTATIC.
field
A String specifying the name of the AnalyticalField object associated with this load.
The *field* argument applies only when *distributionType*=FIELD. The default value is an
empty string.
amplitude
A String or the SymbolicConstant UNSET specifying the name of the amplitude reference.
UNSET should be used if the load 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 whether the load is uniform. Possible values are UNIFORM,
HYDROSTATIC, USER_DEFINED, and FIELD. The default value is UNIFORM.
side
A SymbolicConstant specifying whether the pressure is applied internally or externally.
Possible values are INTERNAL and EXTERNAL. The default value is INTERNAL.
Returns
