Defining output requests in an Abaqus/Standard analysis
One of the following mutually exclusive parameters is required
- DIAGNOSTICS
-
Set DIAGNOSTICS=YES (default) to indicate that detailed diagnostic information should be written to the output database. Set DIAGNOSTICS=NO to suppress the output.
- FIELD
-
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.
- HISTORY
-
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.
Optional parameters
- FREQUENCY
-
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. Set FREQUENCY=0 to suppress the output.
If this parameter and the NUMBER INTERVAL, TIME INTERVAL, and TIME POINTS parameters are omitted, output will be written at 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.
The FREQUENCY, NUMBER INTERVAL, TIME INTERVAL, and TIME POINTS parameters are mutually exclusive.
- MODE LIST
-
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, and if the FIELD parameter is included.
- NAME
-
Set this parameter equal to the name associated with this output definition.
- NUMBER INTERVAL
-
Set this parameter equal to the number of intervals during the step at which the output database states are to be written.
If this parameter and the FREQUENCY, TIME INTERVAL, and TIME POINTS parameters are omitted, output will be written at 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.
The FREQUENCY, NUMBER INTERVAL, TIME INTERVAL, and TIME POINTS parameters are mutually exclusive.
- TIME MARKS
-
Set TIME MARKS=YES (default) to write results at the exact times dictated by the NUMBER INTERVAL, TIME INTERVAL, or TIME POINTS parameter.
Set TIME MARKS=NO to write results to the output database at the increment ending immediately after the time dictated by the NUMBER INTERVAL, TIME INTERVAL, or TIME POINTS parameter.
- TIME POINTS
-
Set this parameter equal to the name of the TIME POINTS option that defines the time points at which output is to be written.
If this parameter and the FREQUENCY, NUMBER INTERVAL, and TIME INTERVAL parameters are omitted, output will be written at 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.
The FREQUENCY, NUMBER INTERVAL, TIME INTERVAL, and TIME POINTS parameters are mutually exclusive.
The following parameters are optional and valid only if the FIELD or HISTORY parameter is included
- OP
-
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.
- TIME INTERVAL
-
Set this parameter equal to the time interval at which the output states are to be written.
If this parameter and the FREQUENCY, NUMBER INTERVAL, and TIME POINTS parameters are omitted, output will be written at 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.
The FREQUENCY, NUMBER INTERVAL, TIME INTERVAL, and TIME POINTS parameters are mutually exclusive.
- VARIABLE
-
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. Preselected output is ignored in SIM-based dynamic analysis procedures.
If this parameter is omitted, only the variables requested for output with the individual output options will be written to the output database.
The output behavior of the variables included in ALL or PRESELECT cannot be controlled by the parameters or data lines of the individual output options. To get the desired output behavior of a particular variable in an individual output option, the particular variable must be listed in that individual output option.
The following parameter is optional and valid only if the HISTORY parameter is included
- SENSOR
-
Include this parameter to associate this history output request with a sensor definition. The name of the associated sensor is given by the NAME parameter.
Data lines to list desired eigenmodes if the MODE LIST parameter is included
- First line
-
Specify a list of desired eigenmodes.
Repeat this data line as often as necessary. Up to 16 entries are allowed per line.
