Requesting Output to the Output Database

Three types of information are stored in the output database in Abaqus/Standard and Abaqus/Explicit: “field” output, “history” output, and diagnostic information.

This page discusses:

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.

Requesting History Output

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.

Requesting Diagnostic Information

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.
