Comments

1.	When a LIFE command is not present, fatigue life results are not output.

Multiple formats are allowed on the same entry; these should be comma separated. If a format is not specified, this output control applies to all formats defined by the OUTPUT command, for which the result is available. See Results Output by OptiStruct for information on which results are available in which formats.

3.	Multiple instances of this card are allowed; if instances are conflicting, the last instance dominates.
