*MODAL OUTPUT
13.13 *MODAL OUTPUT: Write generalized coordinate (modal amplitude) data to the output
database during a mode-based dynamic or complex eigenvalue extraction procedure.
This option is used during a mode-based dynamic or complex eigenvalue extraction procedure to write
generalized coordinate (modal amplitude and phase) values to the ABAQUS/Standard output database. It
must be used in conjunction with the *OUTPUT, HISTORY option.
Product: ABAQUS/Standard
Type: History data
Level: Step

*OUTPUT
Optional parameter:
VARIABLE
Set VARIABLE=ALL to indicate that all modal variables applicable to this procedure and material
type should be written to the output database.
If this parameter is omitted, the modal variables requested for output must be specified on the
data lines.
Data lines to request modal output:
First line:
1. Give the identifying keys for the variables to be written to the output database. The keys are
defined in the “Modal variables” section of “ABAQUS/Standard output variable identifiers,”
Section 4.2.1 of the ABAQUS Analysis User’s Manual.
Repeat this data line as often as necessary to define the modal variables to be written to the output
database.
