<hr>
<p>
<b>PLOT3D_IO</b>
is a FORTRAN90 library which
reads and writes
<a href = "../../data/plot3d/plot3d.html">PLOT3D files</a>.
</p>
<p>
<b>PLOT3D</b> is a program developed by Pieter Buning at the NASA
Ames laboratory, that performs fluid flow calculations
in one, two or three dimensions. The program is able to save the
results of its calculations in data files that may then be processed
by the FAST graphics program, or converted for use by other graphics
processors. There are a variety of file formats available:
<ul>
<li>
formatted or binary data;
</li>
<li>
the spatial dimension (1D, 2D or 3D);
</li>
<li>
the number of user-defined auxiliary variables;
</li>
<li>
the use of blanking to delete portions of the grid;
</li>
<li>
the storage of 3D data as a whole, or by planes.
</li>
</ul>
</p>
<p>
<b>PLOT3D_IO</b> is a simple package of utility routines for working with
the PLOT3D graphics files. The current set is restricted to
reading data from most binary formats.
