-
Display the concentrated force load editor using one of the following
methods:
-
Click the arrow to the right of the Distribution
field, and select the option of your choice from the list that appears:
-
Select Uniform to define a load that is
uniform over the region.
-
Select an analytical field to define a spatially varying load.
Only analytical fields that are valid for this load type are displayed in the
selection list. Alternatively, you can click
to create a new analytical field. (See
The Analytical Field toolset
for more information.)
-
In the CF1, CF2, and
CF3 text fields, enter the components of the
concentrated force in each direction (units F):
If you leave a text field blank, a force of zero is assigned to that
direction automatically. However, you must enter at least one nonzero component
in the editor to define the load.
-
If desired, click the arrow to the right of the
Amplitude field, and select the amplitude of your choice
from the list that appears. Alternatively, you can click
to create a new amplitude. (See
The Amplitude toolset
for more information.)
-
If desired, toggle on Follow nodal rotation to
make the direction of the load rotate with the rotation at this node.
Follow nodal rotation affects only nodes that
have rotational degrees of freedom and steps in which the
Nlgeom setting is turned on.
-
If you want to change the coordinate system
(CSYS) for the concentrated force load, click
and use one of the following methods:
-
Select an existing datum coordinate system in the viewport.
-
Select an existing datum coordinate system by name.
-
From the prompt area, click Datum CSYS
List to display a list of datum coordinate systems.
-
Select a name from the list, and click
OK.
-
Click Use Global CSYS from the prompt area
to revert to the global coordinate system.
This coordinate system editing option is available only in the step
in which the concentrated force load is created. By default, the global
coordinate system is used to define the load.
-
Click OK to save your data and to exit the
editor.
