The _s#_d.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.

                            Displacement results from
                                frequency response analyses.  Output is controlled by the I/O

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:

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.
