You can request inertia relief whole model variable output to the data or output database file (see “Element output” in “Output to the data and results files,” Section 4.1.2, and “Element output” in “Output to the output database,” Section 4.1.3). Since these variables have unique values for the entire model, the variable output is independent of the specified region.

# Mass diffusion analysis

If you specify an output region, the variable is calculated over the user-specified region. If you do not specify an output region, the variable is calculated as the total over the entire model.

# Total energy output quantities
|
||
|
||
If the following whole model variables are relevant for a particular analysis, you can request them as output to the data, results, or output database file (see “Total energy output” in “Output to the data and results files,” Section 4.1.2, and “Total energy output” in “Output to the output database,” Section 4.1.3). If you do not specify an output region, whole model variables are calculated. When you specify an output region, the relevant energy totals are calculated over the user-specified region.
|
||
|
||
These variables are not available for eigenvalue buckling prediction, eigenfrequency extraction, or complex frequency extraction analysis. You cannot specify an output region for modal dynamic, random response, response spectrum, or steady-state dynamic analysis.
|
||
|
||
See “Energy balance,” Section 1.5.5 of the Abaqus Theory Guide and “Energy computations in a contact analysis,” Section 1.1.25 of the Abaqus Example Problems Guide, for details of the energy definitions. In steady-state dynamics all energy quantities are net per-cycle values, unless otherwise noted.

# Overview
|
||
|
||
Except for the information in the status file, results can be obtained from Abaqus/Explicit only by postprocessing.
|
||
|
||
The tables in this section list all of the output variables that are available in Abaqus/Explicit. These output variables can be requested for output to the results (.fil) file (see “Output to the data and results files,” Section 4.1.2) or as either field- or history-type output to the output database (.odb) file (see “Output to the output database,” Section 4.1.3). In general, output variables that can be requested as fieldor history-type output to an output database in ODB format can also be requested as output in SIM format (see “The output database” in “Output,” Section 4.1.1). When the output variables are requested for output to the results file, Abaqus/Explicit will first output these variables to the selected results (.sel) file and will then convert the selected results file to the results file after the analysis completes.

||

||
# Symbols used in the tables

||
|
||
The availability of the various output variable identifiers is defined by a in the columns of the table, under the following headings:
|
||
|
||
.fil
|
||
|
||
means that the identifier can be used as a results file output selection.
|
||
|
||
.odb Field
|
||
|
||
means that the identifier can be used as a field-type output selection to the output database.
|
||
|
||
.odb History
|
||
|
||
means that the identifier can be used as a history-type output selection to the output database.

# Direction definitions
|
||
|
||
The direction definitions depend on the variable type.
|
||
|
||
<!-- source-page: 770 -->
|
||
|
||
# Direction definitions for element variables
|
||
|
||
For components of stress, strain, and similar material variables, 1, 2, and 3 refer to the directions in an orthogonal coordinate system. These are global directions for solid elements, surface directions for shell and membrane elements, and axial and transverse directions for beam and pipe elements. However, if a local orientation (“Orientations,” Section 2.2.5) is associated with the elements for which output is being requested, 1, 2, and 3 are local directions.
|
||
|
||
# Direction definitions for nodal variables
|
||
|
||
For nodal variables, 1, 2, and 3 refer to the global directions (1=X, 2=Y, 3=Z except for axisymmetric elements, in which case 1=R, 2=Z). Even if a local coordinate system has been defined at a node (“Transformed coordinate systems,” Section 2.1.5), the data in the results file and the selected results file are still output in the global directions.
|
||
|
||
If nodal field output is requested for a node that has a local coordinate system defined, a quaternion representing the rotation from the global directions is written to the output database. Abaqus/CAE automatically uses this quaternion to transform the nodal results into the local directions. Nodal history data written to the output database are always stored in the global directions.
|
||
|
||
# Direction definitions for integrated variables
|
||
|
||
For components of total force, total moment, and similar variables obtained through integration over a surface, the directions 1, 2, and 3 refer to directions in an orthogonal coordinate system. A fixed global coordinate system is used if the surface is specified directly for the integrated output request. If the surface is identified by an integrated output section definition (see “Integrated output section definition,” Section 2.5.1) that is associated with the integrated output request, a local coordinate system in the initial configuration can be specified and can translate or rotate with the deformation.
|
||
|
||
# Distributed load output and user subroutines
|
||
|
||
Output can be requested for many of the distributed loads discussed in “Loads,” Section 34.4. However, contributions to these loads defined through user subroutines (see “Abaqus/Explicit subroutines,” Section 1.2 of the Abaqus User Subroutines Reference Guide) are not displayed.
|
||
|
||
# Principal value output
|
||
|
||
Output of the principal values can be requested for stresses, logarithmic strains, and nominal strains. Either all principal values or the minimum, intermediate, or maximum values can be obtained. All principal values of tensor ABC are obtained with the request ABCP, and the minimum, intermediate, and maximum principal values are obtained with the requests ABCP1, ABCP2, and ABCP3, respectively. For three-dimensional, plane strain, and axisymmetric elements all three principal values are obtained. For plane stress, membrane, and shell elements only the in-plane principal values are obtained for historytype output, and the out-of-plane principal value cannot be requested. For field-type output, all three principal values are obtained through Abaqus/CAE. Principal values cannot be obtained for beam, pipe, and truss elements, and principal values of plastic strains cannot be requested.
