Three types of information are stored in the output database in
Abaqus/Standard
and
Abaqus/Explicit:
“field” output, “history” output, and diagnostic information.
Field output and history output are controlled by output database requests
as described in this section. A subset of the diagnostic information that is
written to the message file for
Abaqus/Standard
analyses and to the status and message files for
Abaqus/Explicit
analyses is included in the output database.
Field output is intended for infrequent requests for a large portion of
the model.
Only complete sets of basic variables (for example, all the stress or strain
components) can be requested as field output.
History output is intended for relatively frequent output requests for
small portions of the model.
Individual variables (such as a particular stress component) can be requested.
Diagnostic information in
Abaqus/Standard
and
Abaqus/Explicit
is intended to provide analysis warning and/or error information.
Output database requests can be repeated as often as necessary within a step
to produce both field and history output at multiple frequencies.
Requesting Field Output
Contact surface output, element output, nodal output, and radiation output
are available as field output in
Abaqus/Standard
and
Abaqus/Explicit.
Input File Usage
Use the first option in conjunction with one or more of the
subsequent options to request field output to the output database:
Contact surface output, element output, energy output, integrated output,
time incrementation output, modal output, nodal output, and radiation output
are available as history output in
Abaqus/Standard
and
Abaqus/Explicit.
Requesting large amounts of history output (more than 1000 output requests)
may cause performance to degrade in
Abaqus/Standard
and will cause performance to degrade in
Abaqus/Explicit.
For vector- or tensor-valued output variables each component is considered to
be a single request. In the case of element variables history output will be
generated at each integration point. For example, requesting history output of
the tensor variable S (stress) for a C3D10M element will generate 24 history output requests: (6 components)
× (4 integration points). When requesting history output of vector- and
tensor-valued variables, it is recommended that individual components be
selected where available.
Input File Usage
Use the first option in conjunction with one or more of the
subsequent options to request history output to the output database:
By default, a subset of the diagnostic information that is written to the
message file for
Abaqus/Standard
analyses and to the status and message files for
Abaqus/Explicit
analyses is also written to the output database.
Input File Usage
Use the following option to write diagnostic information to
the output database:
