Integrated variables

You can request integrated variable output to the output database (see “Integrated output” in “Output to the output database,” Section 4.1.3). The output quantity is computed by integration over a surface or an element set that is specified either directly in the integrated output request or by associating an integrated output section definition (see “Integrated output section definition,” Section 2.5.1) or an element set definition with the integrated output request.

The components of the vector output variables are given with respect to a global coordinate system when no integrated output section definition is associated with the integrated output request. When an integrated output section is associated with the integrated output request and a local coordinate system is defined for the integrated output section, the components are given in the local system. The local system will rotate with the deformation if a reference node with rotation degrees of freedom is associated with the section definition.

Overview

Results can be obtained from Abaqus/CFD only by postprocessing.

The tables in this section list all of the output variables that are available in Abaqus/CFD. The output variables can be requested for either field- or history-type output to the output database (.odb) file (see “Output to the output database,” Section 4.1.3). 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. The field type variables can be requested at the nodes, elements, or element faces attached to a surface.

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:

.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.

Direction definitions for element variables

For element variables, 1, 2, and 3 refer to the global directions (1=X, 2=Y, and 3=Z). Even if a local coordinate system has been defined at a node (“Transformed coordinate systems,” Section 2.1.5), the data are still output in the global directions.

Direction definitions for nodal variables

For nodal variables, 1, 2, and 3 refer to the global directions (1=X, 2=Y, and 3=Z). Even if a local coordinate system has been defined at a node (“Transformed coordinate systems,” Section 2.1.5), the data are still output in the global directions.

Requesting output of components

Individual components of variables can be requested as history-type output in the output database for X–Y plotting in Abaqus/CAE. Individual component requests are not available for field-type output. If a particular component is desired for contouring in Abaqus/CAE, request field output of the generic variable (e.g., V for velocity). Output for individual components of this field output can then be requested within the Visualization module of Abaqus/CAE.

Element variables

You can request element variable output to the output database file (see “Element output” in “Output to the output database,” Section 4.1.3).
