Description:

    The EJ65 file format interface is for 3D body fitted
    coordinate flowfield and mesh data.
    This module is a Reader for the EJ65 geometry and field data,
    in FORTRAN. It accesses the files via interactive browsers,
    and reads the  binary files directly into the AVS session.
    The two browsers are for the mesh and flow field files.
    They are combined on one output port.
    The module is automatic, and follow the input array
    dimensions, but must be compiled with an interal array size
    to match the largest expected field.
    Two types of input are supported, native floating point
    format of the host machine (double precision), and
    if the host is bigendian, then native CONVEX non-IEEE binary
    input is supported, using the optional mode.
    By default, the flow solution data is moved 1/2 a cell to
    the node positions. If requested, it is left at the cell
    centers, and nodal values are calculated by nearest cell
    interpolation. The interpolation mode is untested.

    The Freeze button us used to set new flow or mesh files, or
    other parameters on the module, before attempting the read.
    Both files are accessed, regardless of the parameter change.

    The EJ65 file format is in use at a number of sites,
    including British Aerospace, PLC, UK

    Note: two user-alterable areas are marked in the source,
     one to change the array dimensions of your problem,
     and the other OPEN keywords, may be system dependent.

    This has been tested on a Silicon Graphics Indigo.

Controls:

    Mesh Filename:         <browser>
    Flow Field Filename:   <browser>
    Non-IEEE Convex:       boolean
    Freeze:                boolean
    Interpolate            boolean
