_s#_d.#.frf file
The _s#_d.#.frf file is an OptiStruct ASCII format results file.
File Creation
This file is only created for frequency response optimization. Output is controlled by the I/O Option DISPLACEMENT and OUTPUT,HGFREQ.
File Contents
This file contains the displacement results from frequency response optimization.
File Format
If the real and imaginary format was selected on the DISPLACEMENT 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 DISPLACEMENT 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
- 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
- The first # in the file name is the user-defined subcase ID.
- The second # in the file name is the iteration number.
- The _freq.#.mvw HyperView script file automatically creates plots for the results contained in this file.
