unbalanced gas/luquid conversion rate ?

    I'm new to TPT, so please go easy.

    I have a closed system oil->gas->oil simulation where the amount of oil and gas drops over time.

    It would appear that the oil to gas and gas to oil conversion rate is not constant. Is this a known 'feature' of TPT ?

    um... it's not dropping? it's staying at the same amount of particles for me...

    You may need to wait longer. The debug view settles at about 4400 particles after starting, then after about 5 minutes at 60FPS the particle count has dropped to about 3800. After 10 minutes there is not enough oil to go up the pipe (debug shows about 3400 particles).

    This is with TPT 65.5 under Linux and Windows.

    When a particle is inside a particle of PIPE, it counts as 1 particle, not 2.

    It looks like there may be a bug with the wall that allows liquids to pass. If the liquid is being vapourised then some particles get eaten by the system.

    I have a simple simulation that demonstrates this:

    Found why :
    If the oil is vaporised when it's in the liquid only wall, it will destroyed.
