_s#_a.#.frf file

The _s#_a.#.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 ACCELERATION and OUTPUT,HGFREQ.

File Contents

This file contains the acceleration results from frequency response optimization.

File Format

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

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

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 first # in the file name is the user-defined subcase ID.

2.	The second # in the file name is the iteration number.

3.	The_freq.#.mvw HyperView script file automatically creates plots for the results contained in this file.
