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.

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 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 pore pressure magnitude. The default value is 0. The *magnitude*
argument is optional if *distributionType*=USER_DEFINED.
distributionType
A SymbolicConstant specifying how the boundary condition is distributed spatially.
Possible values are UNIFORM, USER_DEFINED, and FIELD. The default value is UNIFORM.
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.
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.
Returns
-------
A PorePressureBC object.

Parameters
----------
stepName
A String specifying the name of the step in which the boundary condition is modified.
magnitude
A Float or the SymbolicConstant FREED specifying the pore pressure magnitude.
amplitude
A String or a SymbolicConstant specifying the name of the amplitude reference. Possible
values for the SymbolicConstant are UNCHANGED and FREED. UNCHANGED should be used if the
amplitude is propagated from the previous analysis step. FREED should be used if the
boundary condition is changed to have no amplitude reference. You should provide the
