<br>
I'm wondering what FLash does when a simulation is configured without <br>
the cooling module. Does flash solve the energy equation without the <br>
cooling and heating terms? Do you know if using such a configuration<br>
<br>
plus an equation of state with gamma=5/3 is equivalent to a adiabatic <br>
simulation ?<br>
<br>
