Quote:Is it possible that the smoke travelling trough the grid creates (through heat or pressure) some sort of a tunnel that after a while influences the shape of the smoke?
that makes totally sense to me.
I had that problem with explosions when you want to make mushrooms or bubble like fire rolling up. the first one is easy, but if you try to do a second one at the same place, it does not work. I also tought that it's because after the first one there is this tunnel of velocities that drags instead of slowing down the outer parts of the fuel and smoke.
