<p>Hi Andy,</p>
<p>I tried to follow LaserSlab example and I can create three materials "CDN", "GasR", "GasB". In the log file, I do see the Multifluid database contents.
</p>
<p>Initially defined values of species:<br>
Name Index Total Positive Neutral Negative bind Ener Gamma eosType<br>
cdn 13 2.70E+01 1.30E+01 -9.99E+02 -9.99E+02 -9.99E+02 1.40E+00 321<br>
gasb 14 4.00E+00 2.00E+00 -9.99E+02 -9.99E+02 -9.99E+02 1.67E+00 321<br>
gasr 15 4.00E+00 2.00E+00 -9.99E+02 -9.99E+02 -9.99E+02 1.67E+00 321</p>
<p>In the export file, I also have three materials occupying at the right locations. However, I found that it still uses the global "gamma", not ms_CDNGamma, ms_GasBGamma, ms_GasRGamma. Also, it still uses A=1 for calculating the pressure from given density
and temperature. </p>
<p>In the Config file, I have:</p>
<p>REQUIRES physics/Hydro<br>
REQUIRES physics/Eos/EosMain/Gamma<br>
REQUIRES Multispecies</p>
<p>I couldn't figure out why the ms_CDNA, ms_GasBA, and ms_GasRA are not used in the program. Any suggestions? Thank you.</p>
<p>Best,</p>

<p><span style="font-size:11pt">Hi all,<br>
<br>
I am simulating a pure hydrodynamic problem at this point. Therefore, I <br>
modified the example "FlatPlate" for my simulations. In that example, I <br>
specified the pressure and the density of the gas. Then, the temperature <br>
is calculated somewhere in the program. I found that the average atomic <br>
mass is A=1. However, I would like to simulate an Argon gas, i.e., A=40, <br>
but I couldn't find a place to define the average atomic mass. Do anyone <br>
know how I can define the average atomic mass? Thank you.<br>
<br>
Cheers,<br>
