*MODAL FILE
13.12 *MODAL FILE: Write generalized coordinate (modal amplitude) data or eigendata to
the results file during a mode-based dynamic or eigenvalue extraction procedure.
This option is used during mode-based dynamic or eigenvalue extraction procedures to control the writing
of generalized coordinate (modal amplitude and phase) values or eigendata to the ABAQUS/Standard results
file.
Product: ABAQUS/Standard
Type: History data
Level: Step
Reference:
•
“Output to the data and results files,” Section 4.1.2 of the ABAQUS Analysis User’s Manual
Optional parameter:
FREQUENCY
This parameter is valid only in mode-based dynamic procedures.
Set this parameter equal to the output frequency, in increments. The output will always be
written to the results file at the last increment of each step unless FREQUENCY=0. The default is
FREQUENCY=1. Set FREQUENCY=0 to suppress the output.
Data lines to request modal output in the results file during mode-based dynamic procedures:
First line:
1. Give the identifying keys for the variables to be written to the results file. 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 write eigendata during an eigenvalue extraction procedure:
No data lines are required; the eigendata are written automatically.
