You can request three kinds of results from an Abaqus analysis: field output, history output, and report output.

• Field output is the output of variables that are written relatively infrequently to the output database file. Typically, you request field output for your entire model or for a large region. When you create the first step in an Abaqus analysis case, Abaqus for CATIA V5 creates a default field output request that is propagated to subsequent steps. Field output requests generate the data used to produce Abaqus results images.

• History output is the output of variables that are written relatively frequently to the output database—as often as every increment. Typically, you request history output for a small area of your model, such as a single integration point or a small region. History output is not requested by default.

• Data output or report output is the output of variables that are written to the data (.dat) file. By default, input file processor output and output based on the current analysis procedure are written to the data file—the default data output request does not appear in the specification tree. When you request additional data output, Abaqus for CATIA V5 creates a data output request and adds the requested information to the data file during the analysis of your model.

You can modify all three types of output requests in each step to change the output variables or the output frequency. You can deactivate an output request for a step and activate it in a later step. You can delete an output request in the step in which it was created.

The output requested in a general step is independent of the output requested in a linear perturbation or frequency step. Otherwise, the propagation behavior for output requests is the same as the propagation behavior for prescribed conditions described in Propagation.

Abaqus for CATIA V5 creates a default field output request for the first step of each type (general, linear perturbation, or heat transfer) in your model. You can modify or delete the default request, create additional field output requests, or create history output requests. Abaqus for CATIA V5 propagates the output requests created in a step to all subsequent steps of the same type. For example, if you add a history output request to a general step, Abaqus for CATIA V5 propagates your request to all subsequent general steps but not to any linear perturbation or frequency steps. Likewise, if you modify an output request, your change is propagated to all subsequent steps of the same type.

The following sections discuss the use of output requests in Abaqus for CATIA V5:

Creating and Modifying Field Output Requests: Creates or modifies a field output request in the current analysis step.

Creating and Modifying History Output Requests: Creates or modifies a history output request in the current analysis step.

Creating and Modifying Data File Output Requests: Creates or modifies a data output request in the current analysis step.
