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 or a Complex specifying the pressure magnitude.Note:*magnitude* is optional if
*distributionType*=USER_DEFINED.
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 or DiscreteField object associated
with this load. The *field* argument applies only when *distributionType*=FIELD or
*distributionType*=DISCRETE_FIELD. The default value is an empty string.
refPoint
A Region specifying the reference point from which the relative velocity is determined
when *distributionType*=STAGNATION or VISCOUS.
distributionType
A SymbolicConstant specifying how the pressure is distributed spatially. Possible values
are UNIFORM, USER_DEFINED, FIELD, HYDROSTATIC, STAGNATION, VISCOUS, TOTAL_FORCE, and
DISCRETE_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 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.
Returns
-------
A Pressure object.

Parameters
----------
stepName
A String specifying the name of the step in which the load is modified.
magnitude
A Float or a Complex specifying the pressure magnitude.
hZero
A Float specifying the height of the zero pressure level when

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
load has no amplitude reference. You should provide the *amplitude* argument only if it
is valid for the specified step.
