Authors: William M. Chan

Usage:

qed

Description:

The qed (q-editor) program is a menu driven program to perform operations on PLOT3D or OVERFLOW solution files. The program uses the FFIO library to automatically determine the input file attributes (single/double precision, big/little endian, single/multiple grid format, q file type). The following operations can be performed on all or selected grids in the input q file.

 1 = Exit from this menu and program
 2 = Interchange J and K grid families
 3 = Interchange K and L grid families
 4 = Interchange J and L grid families
 5 = Reverse index direction in J and/or K and/or L
 7 = Mirror velocity vector about x=0, y=0 or z=0 plane
 8 = Rotate velocity vector about x, y, z, any arbitrary axis,
     using a prescribed 3x3 matrix, or
     using 1, 2, or 3 successive rotation transforms about x, y, or z axis
