I'm attempting to model the effects of having a smalllightweight ball in a flow to see what happens. The ball needs toreact to gravity and the flow, as well as the surrounding objects.How might I go about doing this? Will this take up a lot of memorywhen I model it? Any help would be appreciated

Thanks,

James
This really depends on what your goal is.

If you are interested in seeing where the ball travels in the flow, and you can assume that it has no impact the flow (ie just along for the ride), then you can use a particle study to inject spheres of a certain mass and size into the flow and watch where they go based on inertia, gravity, flow velocity, etc.

If this is like the ball valve in a shop vac, then it cannot be modeled where it moves as a function of time (and force/pressure) during a simulation. FloWorks assumes that the meshed parts stay in place during a simulation (Rotating regions use a rotational coordinate system to work around this).

Cheers,
