The _s#_v.frf file is an OptiStruct ASCII format results file.

File Creation

This file is only created for frequency response subcases. Creation of this file is controlled by the I/O Option OUTPUT.

Result

Description

Velocity

Velocity results from frequency response analyses.  Output is controlled by the I/O Option VELOCITY.

File Format

If the real and imaginary format was selected on the VELOCITY card, the file starts with the following header:

Frequency"REA | X Trans"IMA | X Trans"REA | Y Trans"IMA | Y Trans"REA | Z Trans"IMA | Z Trans

If the phase and magnitude format was selected on the VELOCITY card, the file starts with the following header:

Frequency"PHA | X Trans"MAG | X Trans"PHA | Y Trans"MAG | Y Trans"PHA | Z Trans"MAG | Z Trans

In either case, the results are grouped by node with results for different nodes separated by a blank line. The format of each line after the header is as follows:

 

Frequency

X-rl/ph

X-im/mag

Y-rl/ph

Y-im/mag

Z-rl/ph

Z-im/mag

where:

Frequency

is the frequency at which results are calculated.

X-rl/ph

is either the real component in the x-direction or the phase angle in the x-direction component.

X-im/mag

is either the imaginary component in the x-direction or the magnitude in the x-direction component.

Y-rl/ph

is either the real component in the y-direction or the phase angle in the y-direction component.

Y-im/mag

is either the imaginary component in the y-direction or the magnitude in the y-direction component.

Z-rl/ph

is either the real component in the z-direction or the phase angle in the z-direction component.

Z-im/mag

is either the imaginary component in the z-direction or the magnitude in the z-direction component.

Comments

1.The # in the file name is the user-defined subcase ID from which these results are obtained.
2.The _freq.mvw HyperView script file automatically creates plots for the results contained in this file.
