Context:
You can specify free body options that are common to all view cuts or that
are specific to a particular view cut.
Abaqus/CAE
can calculate the resultant force and moment by cutting through a display
group, an element set, or the whole model. You can also customize the content
and appearance of all free body cuts in the current viewport; see
Customizing general display options for free body cuts.
Display of resultant force and moment data is available for view cuts of
output databases only. You cannot display this data for view cuts when a model
from the current model database is displayed in
the Visualization module.
By default,
Abaqus/CAE
displays the resultant force and moment only once for each view cut for which
you toggle on display of the resultant force and moment. If desired, you can
also display a series of vectors that show the resultant force and moment data
at regular intervals through the entire model or through a portion of the
model.
From the main menu bar in
the Visualization module,
select .
The View Cut Options dialog box appears.
Click the Free Body tab.
If you are defining cut-specific options, select Use these
options.
From the Computation based on options:
-
Select Cutting through a display group and
select a display group to compute the resultant force and moment based on a
view cut through the selected display group. By default, the current display
group is selected.
- Select Cutting through an element set and
select an element set in the output database to compute the resultant force and
moment based on a view cut through the selected set.
-
Select Cutting through the whole model to
compute the resultant force and moment based on a view cut through the entire
model.
If desired, customize the summation point or the coordinate system
transformation options for the resultant force and moment vectors arising from
view cuts.
-
From the Summation point options, select the
three-dimensional location from which the resultant force and moment vectors
originate.
-
Select Centroid of cut to place the
summation point automatically at the centroid of the surface of the view cut.
-
Select User-defined, and specify a custom
three-dimensional location in space or click
to select the summation point from the viewport. The
summation point is highlighted in the viewport.
-
From the Component resolution options, you
can specify the coordinate system transformation that takes place when vectors
are displayed in component form. (See
Customizing general display options for free body cuts,
for more information about displaying force and moment vectors in component
form.)
-
Select Normal and tangential to orient
the component vectors with the normal and the tangent of the surface you
select.
If desired, specify the Y-axis
value of the tangent for the component vectors. This option enables you to
enforce a uniform direction for the tangent vector when you display a series of
free body cuts on view cut slices.
-
Select CSYS and a coordinate system to
transform the component vectors to a custom coordinate system. Alternatively,
you can click Create to create a new datum coordinate
system.
The Component resolution options affect the
display of resultant forces and moments only when component vector display is
selected in the Free Body Plot Options dialog box.
Toggle on Show heat flow rate if available to
display the heat flow rate in terms of energy per time across the view cut.
If you want to customize the content and appearance of the free body
cut displayed on the active view cut and those created using the
Free Body toolset,
click
to access the Free Body Plot Options; this
option is unavailable if you are defining cut-specific options. See
Customizing general display options for free body cuts.
Click OK.
By default, view cuts persist only for the duration of your session.
If you want to retain a view cut that you have defined to make it available in
subsequent sessions, you can save it to an XML
file, to a model database, or to an output database. For more information, see
Managing session objects and session options.
Click Apply to implement your changes.
The view cuts change to reflect your specifications.
By default, your changes are saved for the duration of the session
and will affect all subsequent view cuts in that viewport. If you want to
retain your changes for subsequent sessions, save them to a file. For more
information, see
Saving customizations for use in subsequent sessions.
