NAME
      new_plot3d  - read in a multiblock PLOT3D data set (grid and
                    q-vector.)  This module only reads in multiblocked
                    grids.

SUMMARY
      Name        new_plot3d

      Type        data

      Inputs      none

      Outputs     ucd (data at nodes)

      Parameters  NAME                 TYPE
                  x.dat                file browser
                  q.dat                file browser
                  iblanks              boolean

DESCRIPTION

      This module reads either a formatted or unformatted multiblock 
      PLOT3D data set consisting of the grid and data vector (Q file).
      No corrections are made for block edge overlap and no co-incident
      node removal is attempted between blocks.  The cells of the 
      ucd structure created are all hexahedra.

      Version 1.0 of new_plot3d reads in only one of the possible plot3d
      file types, a multiblock (with or without iblanks) stored in the
      whole field format.  The Q vector is labeled with the default
      names of the primative variables.  A second module similar to
      the unsupported 'extract cfd values' module is planned to compute
      derived properties from the primative variables.  A crude test
      is made to determine whether or not a file is formatted.  This
      may fail on some platforms.

INPUT
      none

OUTPUT
      The output is a ucd data set with data stored at the nodes.

PARAMETERS
      Read x.dat Browser - a file browser to choose the grid file
                           generally (x.dat).  

      Read q.dat Browser - a file browser to choose the q data file
                           generally (q.dat).  

      iblanks  - a boolean parameter to indicate the presence of 
                 iblank values in the data files.
