CFD Utilities Files

Description:

   GRID_FACES extracts the indicated block faces from the input grid
   and/or function file.  All files are 3-space PLOT3D multiblock type.

Control file:

   'grid_faces.inp' should contain the input and output file specs.
   followed by a list of (block, face) pairs, where faces 1 - 6 mean
   imin, imax, jmin, jmax, kmin, kmax respectively.  E.g.:

   GRID_FACES control file
   ---------- Input grid file ----------
   volume.g   ! or none
   T          ! Formatted? [T|F]
   ---------- Input function file ------
   volume.f   ! or none
   T          ! Formatted? [T|F]
   ---------- Output grid file ---------
   surface.g  ! or none
   T          ! Formatted? [T|F]
   ---------- Output function file -----
   surface.f  ! or none
   T          ! Formatted? [T|F]
   ---------- Block/face list ----------
   171 3      ! Read one pair per line to EOF
   172 3

History:

   06/19/03  D. Saunders  Initial adaptation of SCALE_GRID.
   06/01/04       "       Converting face # to dimension # was wrong!
   12/14/04       "       Switched from CFD_IO_PACKAGE to XYZQ_IO package
                          in order to treat function files as for grids.
