This option is used to write contact, element, energy, nodal, or diagnostic output to the output database. In an ABAQUS/Standard analysis it is also used to write modal or radiation output to the output database. In an ABAQUS/Explicit analysis it is also used to write incrementation output to the output database. The *CONTACT OUTPUT, *ELEMENT OUTPUT, *ENERGY OUTPUT, *INCREMENTATION OUTPUT, *MODAL OUTPUT, *NODE OUTPUT, and/or *RADIATION OUTPUT options can be used in conjunction with this option.

Set DIAGNOSTICS=YES (default) to indicate that detailed diagnostic information should be written to the output database. Set DIAGNOSTICS=NO to suppress the output.
Include this parameter to indicate that the output requests used in conjunction with the *OUTPUT option will be written to the output database as field-type output.
Include this parameter to indicate that the output requests used in conjunction with the *OUTPUT option will be written to the output database as history-type output.
This parameter applies only to ABAQUS/Explicit analyses.
Set this parameter equal to the number of intervals during the step at which the output database states are to be written. ABAQUS/Explicit will always write the results at the beginning of the step. For example, if NUMBER INTERVAL=10, ABAQUS/Explicit will write 11 output database states consisting of the values at the beginning of the step and the values at the end of 10 intervals throughout the step. The value of this parameter must be a positive integer or zero. A value of zero suppresses all output. If this parameter is omitted, its value will be set to 20.
This parameter applies only to ABAQUS/Explicit analyses.
Set TIME MARKS=NO (default) to write results to the output database at the increment ending immediately after the time dictated by the NUMBER INTERVAL parameter.
Set TIME MARKS=YES to write results at the exact times dictated by the NUMBER INTERVAL parameter.
TIME MARKS=YES cannot be used when either the FIXED TIME INCREMENTATION or DIRECT USER CONTROL parameter is included on the *DYNAMIC option.
This parameter applies only to ABAQUS/Explicit analyses.
Set this parameter equal to the name of the *FILTER option to be used to filter the element, nodal, contact, fastener interaction, or integrated history output.
Set FILTER=ANTIALIASING to filter the data based on the sampling interval that is specified; in this case the filter does not need to be defined in the model data. If FILTER=ANTIALIASING, the TIME INTERVAL parameter is required and the FREQUENCY parameter cannot be used.
Set this parameter equal to the output frequency, in increments. The output will always be written to the output database at the last increment of each step. If this parameter is omitted in an ABAQUS/Standard analysis, output will be written for every increment of the analysis for all procedure types except *DYNAMIC and *MODAL DYNAMIC. Output will be written every 10 increments for these procedure types. Set FREQUENCY=0 to suppress the output. If both this parameter and the TIME INTERVAL parameter are omitted in an ABAQUS/Explicit analysis, history output will be written at 200 equally spaced intervals throughout the step.
The FREQUENCY and TIME INTERVAL parameters are mutually exclusive.
This parameter applies only to ABAQUS/Standard analyses.
Include this parameter to indicate that a list of eigenmodes for which output is desired will be listed on the data lines. This parameter is valid only in a *FREQUENCY, *COMPLEX FREQUENCY, or *BUCKLE procedure.
Set OP=NEW (default) to indicate that all output database requests defined in previous steps should be removed. New output database requests can be defined.
Set OP=ADD to indicate that the output request being defined should be added to the output requests defined in previous steps.
Set OP=REPLACE to indicate that this output request should replace an output request of the same type (e.g., FIELD) and frequency defined in a previous step. If there is no matching request, this output request will be interpreted as OP=ADD.
This parameter applies only to ABAQUS/Explicit analyses. Set this parameter equal to the time interval at which the output states are to be written.
For history output ABAQUS/Explicit will always write the data values at the beginning and end of the step. If both this parameter and the FREQUENCY parameter are omitted, history output will be written at 200 equally spaced intervals throughout the step. The FREQUENCY and TIME INTERVAL parameters are mutually exclusive for history data.
For field output ABAQUS/Explicit will always write the output at the beginning of the step. If both this parameter and the NUMBER INTERVAL parameter are omitted, field output will be written at 20 equally spaced intervals throughout the step. The NUMBER INTERVAL and TIME INTERVAL parameters are mutually exclusive.
Set VARIABLE=ALL to indicate that all variables applicable to this procedure and material type should be written to the output database.
Set VARIABLE=PRESELECT to indicate that the default output variables for the current procedure type should be written to the output database. Additional output requests can be defined with the output options used in conjunction with the *OUTPUT option, listed previously.
If this parameter is omitted, only the variables requested for output with the individual output options will be written to the output database.
