*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.

TypeHistory data

LevelStep

Abaqus/CAEUnsupported; Abaqus/CAE reads output from the output database file only.

Optional parameters

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.

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.
