# DSA

I/O Options and Subcase Information Entry The DSA command can be used in the I/O Options section to request Design Sensitivity Analysis results in a Frequency Response Analysis.

## Format

DSA (TYPE, PEAKOUT, PROPERTY) = SID

## Examples

DSA(DISP,PROPERTY)=12
DSA(VELO,PEAKOUT)=45
DSA(ACCE,PEAKOUT,PROPERTY)=23

## Definitions

Argument Options Description
TYPE <DISP, PRES, VELO, ACCE, ERP> Available options:
DISP (Default)
Displacement
PRES
Pressure
VELO
Velocity
ACCE
Acceleration
ERP
PEAKOUT Default = blank If PEAKOUT is present inside the parentheses of the DSA entry, the filtered frequencies from the PEAKOUT card will be considered for DSA results.
PROPERTY Default = blank If PROPERTY is present: This indicates that design sensitivities represent the change in design response due to a change in design properties (instead of design variables).

If PROPERTY is not present: This indicates that design sensitivities represent the change in design response due to a change in design variables.

SID/ALL <SID, ALL>
SID
Refers to the ID of a SET of type GRIDC.
ALL
Requested values are output for all relevant entities.
