QINFO Version 1.2

Authors: Stuart Rogers, Darby Vicker

Synopsis

qinfo solution-file [-len x] [-air] [-gh2] [-co2] [-m [y]]

Description

The QINFO program reads a PLOT3D or OVERFLOW solution file and prints information about the solution file. The output includes the grid dimensions, header data, and dimensional freestream data. There is also an option to report Qmin/Qmax for each Q. Reporting for a particular grid or only global min/max is available through command-line option -m.

Command-Line Options

The name of the input solution file must be given as the first argument on the command line. The optional command line arguments are:

-len x  designates x as the length in inches of the units of
        the corresponding grid file.  (Default = 1.0)
-air    designates that the freestream fluid is air (default)
-gh2    designates that the freestream fluid is gaseous hydrogen
-co2    designates that the freestream fluid is carbon dioxide
-m [y]  compute the min and max for each q variable. (Default: all)
          y=global      : report only the global minmax.
          y=grid number : report minmax for grid number.
                          grid number=0 means report all grids.
          y=all         : report minmax for all grids and global minmax.
 -v      verbose (specify multiple times to increase verbosity)
         Reports file attributes.

File formats

The input file format is detected by the code automatically. This includes:

     Ascii/Unformatted.
     Little/Big Endian for unformatted files.
     Single/Double precision for unformatted files.
     Single/Multiple grid file.
     2D/3D.
     plot3d/Overflow/Overflow-2/Overflow-2 with 2nd order rstart data.

Only 3D unformatted files are processed. Output file format is same as input file format.
