Creating source of liquid particles

[Leonid Lunin]

Hello,

I want to make a simulation with a stream of liquid, for example a faucet in sink. As I unerstood there is a special function for making source of gases, but for liquids it's not. A possible soluation, that I can imagine,  could be generating a given field of particles with given velocities and coordinate for every dt (time step).

Is there any more elegant way?

Thanks in advance

Hello,

One way to achieve a continuous inflow of liquid is to repeatedly sample new particles. For example, by placing `sampleLevelsetWithParticles()` in your simulation loop.
The phi argument of that function would define the inflow area. It could be derived from a `Shape` with the `computeLevelset()` function.

If you want to give your inflow some initial velocity, I recommend using `setSource()` before calling the sampling function. This way all new particles will be initialized with the velocity from the source grid.

Hope this helps,

Best wishes,
Sebastián
