<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>
<br>
