<p class=MsoNormal style='margin-right:-9.0pt'><b>
README FOR CEA2 BATCH JOBS</b></p>
<p class=MsoNormal align=center style='margin-right:-9.0pt;text-align:center'><b> </b></p>
<p class=MsoNormal> </p>
<p class=HTMLBody style='text-align:justify'>CEA2 is slightly different than
the NASA Glenn program described in NASA RP-1311, Parts I and II. </p>
<p class=HTMLBody style='text-align:justify'>(Manuals are available from this
website). The program now uses an <b><span style='text-transform:uppercase'>include</span></b>
file named <b><i>cea.inc</i></b> </p>
<p class=HTMLBody style='text-align:justify'>which consolidates<span
style='text-transform:uppercase'> <b>parameter</b></span> assignments and <b><span
style='text-transform:uppercase'>common</span></b> variable statements in one
place. </p>
<p class=HTMLBody style='text-align:justify'>Previously these statements were
at the beginning of each subroutine. The <b><span style='text-transform:uppercase'>include</span></b>
file is useful </p>
<p class=HTMLBody style='text-align:justify'>for revising maximum dimensions
and input/output unit assignments. See RP-1311, part II, p39.</p>
<p class=HTMLBody style='text-align:justify'> </p>
<p class=HTMLBody style='text-align:justify'>The FORTRAN source and data are
ASCII files in our anonymous server available at the following URL:</p>
<p class=HTMLBody> </p>
<p class=HTMLBody style='text-indent:.5in'><a
href="ftp://ftp.grc.nasa.gov/users/xxminna/CEA+Fortran/">ftp://ftp.grc.nasa.gov/users/xxminna/CEA+Fortran/</a></p>
<p class=HTMLBody style='text-indent:.5in'> </p>
<p class=HTMLBody>The files you should have downloaded are:</p>
<p class=HTMLBody> </p>
<p class=HTMLBody> <b><i>readme.cea</i></b></p>
<p class=HTMLBody><b><i> cea2.f</i></b></p>
<p class=HTMLBody><b><i> cea.inc</i></b></p>
<p class=HTMLBody><b><i> thermo.inp</i></b></p>
<p class=HTMLBody><b><i> trans.inp</i></b></p>
<p class=HTMLBody><b><i> cea2.inp</i></b></p>
<p class=HTMLBody><b><i> cea2.out</i></b></p>
<p class=HTMLBody><b><i> </i></b></p>
<p class=HTMLBody>Since this program is identical to the one available with the
CEAgui download, you may use that </p>
<p class=HTMLBody>executable called <b><i>FCEA2.exe</i></b> if the platform is
appropriate. Or you may compile <b><i>cea2.f</i></b> with <b><i>cea.inc</i></b>
</p>
<p class=HTMLBody>available in the same directory. Note that compilers are freely
available from the internet.</p>
<p class=HTMLBody> </p>
<p class=HTMLBody>File names have an extension (suffix) defined as follows: </p>
<p class=HTMLBody> </p>
<p class=HTMLBody> Fortran source programs - .f</p>
<p class=HTMLBody> Input files - .inp</p>
<p class=HTMLBody> Output files - .out</p>
<p class=HTMLBody> Files of output parameters for plotting - .plt</p>
<p class=HTMLBody> Include file - .inc</p>
<p class=HTMLBody> Unformatted thermodynamic or transport property
databases - .lib</p>
<p class=HTMLBody> </p>
<p class=HTMLBody>The root names of these files are referred to as prefixes. To
run CEA2, simply type in the name of the </p>
<p class=HTMLBody>executable and CEA2 will interactively ask for the prefix of
the input file.</p>
<p class=HTMLBody> </p>
<p class=HTMLBody>The thermodynamic and transport data files must be
preprocessed to form .lib files before input </p>
<p class=HTMLBody>problem files can be run. The .lib files are obtained by
running the <b><i>thermo.inp</i></b> and <b><i>trans.inp</i></b> </p>
<p class=HTMLBody>as input files. The user types <b>thermo</b> or <b>trans</b>
when CEA2 asks for an input prefix and the </p>
<p class=HTMLBody>required files are created. These files do not need to be
processed again unless the data are revised. </p>
<p class=HTMLBody>The <b><i>thermo.out</i></b> file lists each species name,
the reference/date code, the heat of formation in </p>
<p class=HTMLBody>Joules/mole at 298.15K , and some reference information.</p>
<p class=HTMLBody> </p>
<p class=HTMLBody>You are now ready to run the sample problems <b><i>cea2.inp </i></b>and
check with the sample output <b><i>cea2.out</i></b></p>
<p class=HTMLBody> </p>
<p class=HTMLBody>To get thermodynamic properties of individual species in <b><i>thermo.inp</i></b>
or to download subsets of this </p>
<p class=HTMLBody>data, go to the following URL and see <b><i>About
ThermoBuild</i></b><i> </i>for details.</p>
