[Fontan]

Hello all,

I'm trying to simulate a shock tube on Fluent, but I'm having trouble setting up two independent fluid zones for the driver and the driven. As it is right now, whenever I change the initial conditions for one, the other changes to the sam conditions. Therefore, I cannot set different pressures to make it work.

I know it must be a trivial mistake, but I've searched the forums and the internet and could not find any kind of turorial, so any help is appreciated.
