Domains

You might notice the apparent absence of any domain controls. That is because the solver is domain-less. You don’t need to worry about the bounds of your simulation because it will just start simulating where ever you emit into. Traditional ideas like auto-resize, and padding the way you might be familiar with don’t apply here.

There are however important things to keep in mind when using the sparse volume. I’d recommend checking out the section titled Sparse in the documentation page.
