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.
magnitude
A Float or Complex specifying the load magnitude. *magnitude* is optional if
*distributionType*=USER_DEFINED
distributionType
A SymbolicConstant specifying how the shell edge 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.
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.
angle
A Float specifying an additional rotation of *directionVector* about an axis. The
default value is 0.This parameter is available only if *traction* is GENERAL.
axis
A SymbolicConstant specifying the axis about which to apply an additional rotation of
*directionVector*. Possible values are AXIS_1, AXIS_2, AXIS_3. The default value is
AXIS_1.This parameter is available only if *traction* is GENERAL.
localCsys
A DatumCsys object specifying the local coordinate system of the load's degrees of
freedom. The default value is None, indicating that the degrees of freedom are defined
in the global coordinate system or by the *userCsys* parameter if defined. This
parameter is available only if *traction* is GENERAL. When this member is queried, it
returns an Int.
userCsys
A String specifying a CSYS defined by a user-subroutine. The default value is None,
indicating that the degrees of freedom are defined in the global coordinate system or by
the *localCsys* parameter if defined. This parameter is available only if *traction* is
GENERAL.
directionVector
A tuple of two points specifying the direction of the load. Each point is specified as a
point region or a tuple of coordinates. If *traction* is SHEAR, then *directionVector*
will be projected onto the region surface. This parameter is available only if
*traction* is GENERAL.
follower
A Boolean specifying whether the direction of the force changes with rotation. The
default value is ON. This parameter may be modified only if *traction* is GENERAL. You
should provide the *follower* argument only if it is valid for the specified step.
resultant
A Boolean specifying whether to maintain a constant resultant force by defining traction
per unit undeformed area. If *resultant* is OFF, traction is defined per unit deformed
area. The default value is OFF. You should provide the *resultant* argument only if it
is valid for the specified step.
traction
A SymbolicConstant specifying how to apply surface traction. Possible values are NORMAL,
TRANSVERSE, SHEAR, MOMENT and GENERAL. The default value is NORMAL.
Returns
-------
A ShellEdgeLoad object.
