[FLASH-USERS] adiabatic simulation

[Eddie Hansen]

It depends on other physics you may have turned on. We can write a
simplistic  energy equation as:

d(energy)/dt + grad(energy_flux) = -L

where L is the cooling/heating source term. FLASH will solve the equation
without any cooling/heating (L=0), which would potentially make the system
adiabatic. But there's other physics that can appear on the right hand side
of the equation. And you might also consider the system to not be adiabatic
depending on the boundary conditions being used.
