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 and FIELD. The default value is UNIFORM.
follower: Boolean
A Boolean specifying whether the direction of the force rotates with the rotation at
each node of the region. You should provide the **follower** argument only if it is valid
for the specified step. The default value is OFF.
localCsys: int
None or a :py:class:`~abaqus.Datum.DatumCsys.DatumCsys` object specifying the local coordinate system of the load's degrees
of freedom. If **localCsys=None**, the degrees of freedom are defined in the global
coordinate system. When this member is queried, it returns an Int. The default value is
None.
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
