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.
File Contents
| 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:
| |
Frequency |
X-rl/ph |
X-im/mag |
Y-rl/ph |
Y-im/mag |
Z-rl/ph |
Z-im/mag |
- Data
- Description
- Frequency
- 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
- The # in the file
name is the user-defined subcase ID from which these results are obtained.
- The _freq.mvw
HyperView script file automatically creates plots for
the results contained in this file.
