Attributes
----------
name: str
A String specifying the load repository key.
distributionType: SymbolicConstant
A SymbolicConstant specifying how the load is distributed spatially. Possible values are
UNIFORM, USER_DEFINED, and FIELD. The default value is UNIFORM.
system: SymbolicConstant
A SymbolicConstant specifying whether the load is applied in a global or the beam local
frame of reference. Possible values are GLOBAL and LOCAL. The default value is GLOBAL.
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 load is created.
region
A Region object specifying the region to which the load is applied.
distributionType
A SymbolicConstant specifying how the load is distributed spatially. Possible values are
UNIFORM, USER_DEFINED, and FIELD. The default value is UNIFORM.
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.
comp1
A Float or a Complex specifying the component of the load in the global or the beam
local 1-direction.Note:Although *comp1*, *comp2*, and *comp3* are optional arguments, at
least one of them must be nonzero unless *distributionType*=USER_DEFINED.
comp2
A Float or a Complex specifying the component of the load in the global or the beam
local 2-direction.
comp3
A Float or a Complex specifying the component of the load in the global 3-direction.
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.
system
A SymbolicConstant specifying whether the load is applied in a global or the beam local
frame of reference. Possible values are GLOBAL and LOCAL. The default value is GLOBAL.
Returns
-------
A LineLoad object.

----------
stepName
A String specifying the name of the step in which the load is modified.
comp1
A Float, a Complex, or a SymbolicConstant specifying the load component in the global or
