Hi,

I want to reproduce gas parcles injected into a water tank by a nozzle in the bottom. Parcles are active and coupled with fluid.

What settings should I use in order to reproduce buoyancy motion? I set up sprayCloudProperties in this way:
Code:
constantProperties
{
    parcelTypeId    1;
...
    rho0            1;
...
    constantVolume  false;
}
Code:
    particleForces
    {
        pressureGradient
        {
             U U;
        };
        sphereDrag;
        gravity;
    }
but the parcles just fall to the tank bottom.
