exact times from the Timing field to alter the
time incrementation size to match the time intervals exactly.
From the Output Variables field, choose the
variables and variable components to output:
- Select from list
below
-
Choose this method to select the output variables of interest from the
list of variable categories. Use the following techniques to select particular
variables:
-
In the top half of the editor, click the arrow next to the desired
variable category. From the list of variables that appears, select the
variables of your choice. If a variable of interest has components, click the
arrow next to the variable and select the components of interest. To select or
deselect all components of a variable, toggle the variable itself.
-
Toggle the desired variable category to select or deselect all
variables and variable components within that category.
The check box next to a variable category name becomes completely
filled when all variables within that category are selected as well as all of
the components of those variables. The box becomes half filled if only some of
the variables or variable components within that category are selected.
Likewise, the check box next to a variable name becomes completely filled when
all components of that variable are selected. The box becomes half filled if
only some of the components of that variable are selected.
- Preselected defaults
-
Choose this method to allow
Abaqus/CAE
to select a preselected (default) set of output variables and components
appropriate for the step's analysis procedure.
- All
-
Choose this method to automatically select all of the allowable output
variables and variable components within each variable category in the list.
- Edit
variables
-
Choose this method to enter or delete output variables and components
in the text field located above the list of variable categories.
Note:
In addition to the current analysis procedure, other aspects of the
model may affect the preselected default output variables. For example, if an
output variable is valid for the analysis procedure but is not valid for the
element type used in the mesh,
Abaqus
will remove that variable during the analysis.
If you want to include sensor output, toggle on Include
sensor when available. This option is available when the domain
Set is selected.
Toggle Use global directions for vector-valued
output. This option is available when the domain
Set is selected.
When Use global directions for vector-valued
output is on, nodal history output is requested in the global
directions.
When Use global directions for vector-valued
output is off, nodal history output is requested in the local
directions defined by nodal transformations.
If your domain is set to Whole model,
Set, Skin, or
Stringer do the following:
-
If your model contains rebar and you edit the output request in
the step in which it was created, you can include output for rebar in the field
data that
Abaqus
writes to the output database. From the bottom of the editor, toggle on
Output for rebar and choose one of the following options
that appears:
- Include
-
Choose Include to request that
Abaqus
write output for rebar in addition to output for the underlying material to the
output database.
- Only
-
Choose Only to request that
Abaqus
write only output for rebar to the output database.
If you want to view rebar orientations in
the Visualization module,
you must toggle on Output for rebar.
-
If you edit the output request in the step in which it was
created, you can change the section points from which variables will be output.
From the bottom of the editor, choose one of the following:
- Use
defaults
-
Choose Use defaults to request that
Abaqus
write field data to the output database from the default section points.
Abaqus
chooses the default section points based on the section selected in the
Property module.
(The default section points are usually the outer fibers of the section.) For
more information see
The Property module.
- Specify
-
Choose Specify to enter the section points
for which
Abaqus
will write field data to the output database. The specified section points are
used only during the selected output request;
Abaqus
reverts to the default section points for subsequent output requests.
If your domain is set to Composite layup, specify
the section points from which variables will be output.
Note:
By default,
Abaqus/CAE
writes field output data from only the top and bottom of a composite layup, and
no data from the plies are generated. Therefore, if your model contains a
composite layup and you want data from individual plies, you must create a new
output request or edit the default output request and specify the section
points from which variables will be output.
From the bottom of the editor, choose one of the following:
- Selected
-
Choose Selected points for each ply to request
that
Abaqus
write field data to the output database from the top, middle, and/or bottom
section point of each ply.
- All
-
Choose All section points in all plies to request
that
Abaqus
write field data to the output database from all of the section points of all
of the plies.
- Specify
-
Choose Specify to enter the section points for
which
Abaqus
will write field data to the output database. Section points are numbered
sequentially from the top of the first ply to the bottom of the last ply. For
example, if you have three plies, each with three section points, and you want
output from the middle section point of each ply, you would enter
2,5,8. The specified section points are used
only during the selected output request;
Abaqus
reverts to the default section points for subsequent output requests.
If you edit the output request for an
Abaqus/Explicit
analysis procedure in the step in which it was created, you can apply a filter
to remove high frequency data from the history output.
From the bottom of the editor, toggle on Apply
filter and choose the default Antialiasing
filter or select a named filter that was created using the Filter toolset. For
more information, see
The Filter toolset.
When you have finished defining the output request, click
OK to save your changes.
